Read the free plan's number twice, because the word doing the work is 'lifetime': it is 500 codes in total, not 500 a month.

Two plans, billed in USD every 30 days. Free costs nothing and covers 500 lifetime codes with CSV export. Pro is $14.99 a month and lifts that to unlimited codes per month, with the same CSV export; both plans say they work with most discount applications. The plan table lists no annual rate, no free trial on Pro and no per-code charge, so the monthly figure is the whole cost. Plans change — always verify the live price on their site.

One influencer drop or one email segment can spend the whole allowance in an afternoon, and after that the only way on is $14.99 a month — so the free tier is a sample, not a plan. What the app does is also narrower than the word 'discounts' suggests. It takes a discount you have already created and multiplies it into unique codes you export as a CSV. It does not create the discount rule, does not send the codes to anyone, and does not report which ones were redeemed, so it sits between your discount settings and your email or SMS tool and needs both of those to be worth anything.
The 4.9 rating also rests on 40 reviews, which is a thin record next to the app's peers.
Shopify app (by Optizio) that turns a discount you have already created into thousands of unique codes and exports them as CSV for email and SMS campaigns. Free covers 500 lifetime codes; Pro is $14.99 a month for unlimited codes.

The two plans differ in exactly one line: 500 lifetime codes becomes unlimited codes per month. Every other feature the table names — CSV export, working with most discount applications — is already on the free plan. So this is not a ladder with more product at the top; it is a meter, and Pro switches it off. That makes the sum unusually easy. Work out how many unique codes one campaign burns, and if the answer clears 500 over the life of the store, the free plan was never going to hold and $14.99 a month is the price of the app.
If you send one bulk campaign a quarter and each takes a couple of hundred codes, the free tier may carry you for a year before you have to decide anything.
Installation runs from the App Store, so setup starts inside your Shopify admin rather than at a separate signup, and the app asks to view customer data alongside your discount and order data before it will run. The order of operations matters more here than the setup does: the discount has to exist first. Create the discount you want in Shopify (or in whichever discount app already makes it), then point Code Bulk at it and generate the batch.
Start with a small run of a few dozen codes and push them through your email or SMS tool end to end before you generate thousands, because the free plan's 500 are gone for good once you spend them and there is no trial on Pro to fall back on.
Distilled from The Code Bulk Discounts listing on the Shopify App Store (apps.shopify.com/code-bulk), read 6 September 2026 — the two plans and the wording of the free tier's cap, the absence of any annual rate or trial, the developer (Optizio), the launch date of 24 May 2024, the 4.9 rating over 40 reviews, and the data the app asks for — plus a check of the listing's own Website link, which leads to discountkit.app, a separate and pricier Optizio product rather than a page about this app.
Both columns come from the same place: each vendor’s own published pricing, read on the date shown in the sources at the foot of this page. We do not average them into a score.
Both names above are affiliate links: we may earn a commission if you sign up, at no extra cost to you. Neither changes what this table says: both columns come straight from the vendors’ own pricing pages.
The natural comparison is Kite — Both come out of the Shopify discount aisle and both generate bulk codes, but they are priced for different problems. Code Bulk Discounts does one job — turn an existing discount into unique codes and export them — and asks $14.99 a month once the 500 lifetime free codes run out. Kite treats bulk codes as one feature among many and puts them behind $29 a month, with the code ceilings rising by tier. So if codes are the whole requirement, Code Bulk is the cheaper and simpler answer and there is nothing to grow into. If you also want the discount mechanics themselves — free gifts, BOGO, tiered pricing, progress bars — Code Bulk cannot build any of them and Kite is the one that can..

Check your platform and version specifically. Shopify support is close to universal in this category, while WooCommerce, BigCommerce, Magento and headless setups vary a lot, and 'supported' sometimes means a generic API rather than a maintained app. A listing in your own platform's app store, with recent reviews there, is a better signal than the vendor's logo wall.
