DCBShopify Discount Blocker Apps Compared (2026): DCB vs Alternatives
By Viktoriia Pavlova · · 7 min read
Quick answer
If you need to stop codes on sale items, by tag, on selected products or sitewide on a schedule, compare apps on four things: which rules they support, scheduling, custom error messages and whether they run on Shopify Functions. DCB covers all four.
What a discount blocker app should do
- Block codes for compare-at price (sale) items
- Block by product tag and for selected products
- Block all codes sitewide, ideally on a schedule
- Allow-list specific codes (VIP, staff)
- Show a custom, translatable checkout message
- Run on Shopify Functions so it works with Checkout Extensibility
How to evaluate alternatives
When you look at other apps in the App Store under “discount blocker” or “discount restrictions”, check:
- Do they edit your existing codes (risky) or block at checkout (safe)?
- Is there scheduling for sale windows?
- Recent reviews and how fast the developer replies
- Price per month vs what one stacked order costs you
