Shopify Discount Apps Compared: Vault vs Discounty vs Bold vs BOGOS

The Shopify App Store has upwards of 200 apps filed under “discounts and promotions,” and most of them are forgettable. Four names appear on nearly every mid-market merchant’s shortlist: Vault, Discounty, Bold Discounts, and BOGOS. Each has a distinct shape, earned honestly through design decisions. No one of them wins on every axis; each wins on the axes it was built around.

This piece is a feature matrix for the four, plus the nuance the matrix cannot carry. Written for merchants evaluating discount apps in 2026, not for the apps themselves.

What to actually compare

Before the table, the axes that matter. Discount-app marketing pages lean on feature counts (“46 discount types!”), which is the wrong measurement. The axes that determine whether an app saves or costs a store money:

• Stacking rules. Does the app expose explicit combination logic, or does it rely on Shopify’s coarse native combine/don’t-combine flag?
• Pre-launch audit. Does the app catch unsafe configurations — missing end dates, negative-margin stacks, gift-chain vulnerabilities — before the campaign ships, or only after?
• POS coverage. Does the app propagate discount rules to Shopify POS, and can rules be scoped to location or device?
• Customer-tag and segment gating. Are tag-gated discounts first-class, or a workaround?
• Time-window automation. Can campaigns start and end automatically on a schedule, including recurring windows (Happy Hour, weekly sales)?
• Pricing model. Tiered by feature, by discount volume, by revenue — and where does the ceiling hit for your store size?

Comparison matrix

Four apps, on the axes above, as of April 2026.

Axis	Vault	Discounty	Bold Discounts	BOGOS
Stacking rules	Explicit, rule-by-rule combinability with margin floor	Combine flags plus time-window isolation	Combine flags with rule priorities	BOGO-centric; limited stacking across other types
Pre-launch risk audit	First-class — blocks unsafe configs	Basic validation (missing end dates)	Rule conflict warnings	Not primary focus
POS coverage	First-class, device-scoped	Time-window-aware POS propagation	First-class, location-scoped	Basic, BOGO-focused
Customer-tag gating	First-class	Supported	First-class	Supported for BOGO rules
Time-window automation	Full (start/end, recurring, DST-aware)	Strongest in category	Full	Basic
BOGO / free-gift mechanics	Full, with stack-aware guardrails	Supported	Full	Specialist; deepest BOGO feature set
Volume-tier discounts	Full, with margin floor	Supported	Full	Partial
Group-buy / unlock mechanics	Not supported	Partial	Native (via companion app)	Not supported
Velocity-based escalation	Native	Not supported	Manual only	Not supported
Pricing model	Tiered by campaign complexity	Tiered subscription	Store-tier-based	Free tier, then usage tiers
Best fit	Audit-critical, layered-promo stores	Flash-sale-heavy, time-windowed stores	Broad coverage across discount types	BOGO-centric promotion programmes

The matrix flattens each app; the nuance below is where the real decision lives.

Vault

Built around the observation that most discount-app failures are composition bugs, not logic bugs. The signature feature is the pre-launch audit — every campaign is scored against a catalogue of known failure modes (missing end dates, stackable gift chains, negative-margin pairs, POS/online drift) before it ships. Stacking rules are explicit at the rule level, with a margin floor that the audit cannot be told to ignore.

Best fit for merchants running eight-figure GMV and above with layered promotions across online and POS, where a margin-negative pair going live is a material incident. Less interesting for stores whose promotion programme is simple enough that native Shopify rules would suffice.

Discounty

Strongest in the category for time-windowed and flash-sale mechanics. Scheduling UI is polished, DST handling is correct, recurring-window support is mature. If the store’s promotion programme is centred on flash sales, daily specials, or recurring Happy Hour-style windows, Discounty’s scheduling surface is the differentiator.

Less invested in audit than Vault, and stacking rules are slightly less granular. For a store whose promotion failures are overwhelmingly “sale ended too early or too late,” Discounty removes that class of failure better than the alternatives.

Bold Discounts

The established, broad-coverage choice. Part of the Bold Commerce family, which gives it companion apps for memberships, bundles, and subscriptions that integrate well. Feature coverage across discount types is essentially complete. Stacking is rule-priority-based rather than explicit-pairing, which is a subtly different model — it works, but requires more careful configuration for edge cases.

Best fit for merchants who want one discount system that covers every discount type the store might need, without specialised audit or experimental flash-sale mechanics. A safe default for stores that are not optimising for a single specific dimension.

BOGOS

The BOGO specialist. If more than half of the store’s promotion programme is buy-one-get-one, buy-two-get-one-free, or free-gift-with-purchase mechanics, BOGOS’s depth in that one primitive exceeds what any generalist app can match. The free tier is among the most accessible in the category, which makes it a common first stop for small and mid-market stores.

For stores whose promotions go well beyond BOGO — tiered discounts, complex stacking, customer-tag gating, velocity rules — BOGOS is less well-suited. It is deliberately focused on BOGO mechanics rather than trying to cover the full discount surface.

How to decide

A three-question sort that handles most decisions:

1. Is audit and margin protection a primary requirement?

• Yes → Vault.
• No → continue.

2. Is the promotion programme centred on a specific mechanic (flash sales, BOGO)?

• Flash sales / time-windowed → Discounty.
• BOGO / free-gift → BOGOS.
• Neither → continue.

3. Broad coverage across discount types without specialisation?

• Yes → Bold Discounts.

If two of the three apply, the tie-breaker is usually pricing model and store scale. Vault’s pricing is tuned for mid-market and above; BOGOS’s free tier makes it the easy first-try at the low end. Discounty is strongest for stores whose discount budget is mostly in the scheduling layer. Bold is the default for stores whose criteria is “covers everything without surprising me.”

What the matrix cannot show

A feature matrix is a sorting tool, not a decision tool. Three things to evaluate beyond the matrix:

• Support responsiveness. All four apps have real support teams. Response times vary under peak-season load; evaluate by filing a non-urgent question two weeks before BFCM and seeing how long the real answer takes.
• Cost per prevented incident. One margin-negative campaign during BFCM can cost a mid-market store more than years of any of these apps’ subscription fees. The right pricing lens is incident prevention, not monthly fee.
• Migration story. If you’re already on one of these apps, the cost of migrating matters. Migrations across discount apps are almost always easier at a campaign boundary (end of a major promotional window) than during one.

The underlying point

Discount apps look the same from the outside and are not. Each of these four has a distinct design thesis, and the thesis determines which failures the app will catch for you and which it will leave for your ops team to catch. Pick the app whose thesis matches the failures you most want to prevent.

Vault’s thesis is audit-first — a promotion without an end date is a liability disguised as a campaign, and the engine’s job is to refuse to ship it. If that thesis matches your store, Vault is the right answer. If not, the alternatives above will serve you better than they get credit for.
