Bulk Discount Codes for Shopify

Generate thousands of unique discount codes in minutes — reliably, with CSV/XLSX exports, code import, and the only bulk-codes API on the App Store. One honest flat price.

Built to not break

Large batches run through a job engine with automatic retries and live progress. Nothing fails silently — ever.

Import & export

Bring your own codes by paste, take them away as CSV or XLSX. No email round-trips, no lock-in.

API & webhooks

Create sets and pull unique codes from your loyalty tools, scripts, or automations. No other bulk-codes app has this.

Honest pricing

500 free codes every month, all features included. Unlimited for $8.99/month flat. No metering, no surprises.
