Been using the app for years, and its my go-to on other sites I work on. Support has been great, always helpful and recommend it. Its easy to use and they made a lot of great changes to the UI lately that have made the app more intuitive to use.

I have been a long time user, but every time i need it to work, there's a problem. Maybe they should ensure that the thing works, promptly, without fuss, before adding new bells and whistles. Time to look for something else.
— Blackwell's Wines & Spirits
App glitches when customers trying to sign up for a notification. Requested a refund for one months subscription. No follow up after 35 days.
— CRO WEAR
stop charging me I'm no longer using this app i send a email thank you if you can fix that that would be great!
— sew away
Whatever you do, don't even think about downloading this app. You can't manage anything on your own; you need a customer representative for everything, but there aren't even any to contact. I send emails, and they only respond after three days. It's truly awful. Please don't waste your time using this app.
— REVEA
As a boutique brand with limited runs of goods, AMP has been extremely useful in helping us both secure extra revenue with restocks on products but also defining how much to make. After nearly 10 years of use, it is an indispensable tool for our brand
— Project X
Our company has used Back in Stock (AMP) for 5 years and honestly we can't fault it. The automatic notifications to our customers works so effortlessly, so we don't have to do any work from our end! It's a win win. Highly recommend this app if you're thinking about it.
— Claudia Dean World
We've been using AMP Back in Stock | PreOrder for two days, and my experience has been great so far! Special thanks to Leslie from the AMP Experts team for her patience, guidance, and friendly approach. She helped us understand how the app works, particularly its email settings and custom domain configuration, explaining why things are set up the way they are. We're still learning the app's feat...
