Pricing and trial
Installation is free. The listing charges $1 per set up to 10,000 codes, $3 up to 100,000 and $5 up to 250,000. The FAQ offers the first set up to 10,000 free. No time-limited trial is listed. Pricing.
Rating and reviews
4.4/5 (154 reviews). Checked September 27, 2026. Prices in USD. Merchants like the simple pricing. Feedback also includes slow batch generation and a blocked batch, so create campaign codes ahead of the send date.
Pitfalls
Charges apply per job, not to a pooled code allowance. The FAQ allows only two simultaneous sets and skips duplicate codes. Configure discount combinations in Shopify after generating the set. Documentation.
Conclusion
A practical low-cost choice for occasional bulk coupons. Choose a fuller promotion platform when you need storefront messaging, targeting logic or automatic catalog sales.
