See every featureBastionCart helps Shopify merchants review active discounts before weak promotion settings turn into avoidable margin loss. Run a discount audit to find issues like no end date, unlimited usage, broad eligibility, combinable discounts, missing minimum requirements, and unusually deep percentage-off offers.
Review Shopify discount definitions from a read-only dashboard. StackLens highlights overlapping campaign windows, combination-setting signals, upcoming starts and expirations, reported code-usage limits, and automatic-discount capacity. Each finding shows observed evidence and limitations. It doesn't edit discounts or predict which discount will apply to a cart.

FAQ
BastionCart and StackLens: common questions
- Is BastionCart or StackLens cheaper?
- Only StackLens lists a free plan. Shoplist compares base prices only between monthly plans in the same currency; usage charges and annual plans vary, so check each plan’s limits.
- What features does each app list that the other doesn’t?
- BastionCart lists 1 the others don’t mention, such as Discount stacking. StackLens lists 3 the others don’t mention, such as Analytics, Import and export, Reporting. A feature missing from a listing may still be supported; this compares what each App Store listing says.
- Where does this comparison’s data come from?
- Shoplist crawls Shopify storefronts to detect which apps each store runs, and reads each app’s Shopify App Store listing for reviews, pricing, features and integrations. Store counts are as of Jun 3, 2026 for BastionCart, Oct 13, 2026 for StackLens; estimated figures are labeled.
How Shoplist compares apps
Store counts come from Shoplist’s crawl of Shopify storefronts, which detects the apps each store runs; they are as of Jun 3, 2026 for BastionCart, Oct 13, 2026 for StackLens. Reviews, ratings, plans, features and integrations come from each app’s Shopify App Store listing. 28-day figures are labeled when estimated, and a figure that is missing or estimated never decides who leads.
