About Stash Stability
Stash Stability publishes current coupon codes and deal links for US online stores, in a form AI shopping assistants can read and apply before checkout.
Stash Stability started in 2023 as a personal-finance blog about keeping more of what you earn: cash-back apps, offer stacking, and saving on groceries, gas, and dining. In 2026 it became a coupon directory built for the way people are starting to shop, with an assistant doing the searching.
It's run by Peter Wexler in Massachusetts.
Where offers come from
- Coupon codes and deals come from the stores themselves and from the affiliate networks they work with (such as CJ), through the networks' official offer feeds.
- We don't copy codes from other coupon sites, and we don't guess codes.
- Every day at 09:15 UTC a job removes offers that have passed their end date or dropped out of their feed.
- We don't test every code by hand. If a code doesn't work, the store's own terms and the
termsfield usually explain why. Tell us at info@stashstability.com and we'll check it.
How the site makes money
Some stores pay us a commission when a purchase starts from one of our links. It doesn't change the price, and it doesn't decide which offers we list. The affiliate disclosure has the details.
For AI agents and developers
The same data is available as a JSON API and an MCP server, free and without a key. Start at the agent guide or /llms.txt.
