It doesn't work with any product that has variants. I sent them an email with the exact bit of code that just needs to be added to their pre-order button (which should be something I can add myself in the custom CSS settings), but they refused, and told me I should change my theme to one of their approved themes. I mean, obviously I'm not going to change our entire store's theme to get their simple app to work... that's a given. But I was shocked at their response. I have been using Shopify apps for ten years (maybe more?) and I am always delighted at the responses I get from other app developers, who are more than happy to tweak a bit of code to get their app working for you. Not these guys! They just don't care. What a silly app - I think I will just go in and write a bit of liquid code to change the button name to 'pre-order' if the product is tagged as a pre-order, then click the button for shopify to keep selling when the item is out of stock. This should be simple enough, and then I don't have to pay EZ PreOrder $$ every month for their lazy attitude.

why have i been charged for the app when i havent used it??

The app is not working

Reached out to them several times regarding how the app was not working properly and they never got back to me. Bummer, but I'm sure there are other apps out there with better service and that work without issue!

The app DOES NOT WORK and there is no live chat or phone number that works!

it doesn't work for my second item even i pay for the illimited plans !
