Fair/Square review for Preorder, Back In Stock ‑ STOQ

Very happy with this app. I've been using the free version for a while for out-of-stock notifications. It's very easy to use and works well. I just set up pre-orders for the first time and contacted the chat to have the pre-order buttons visible on a custom page I built. Sneha helped me and within 2 minutes it was all done. Excellent customer service.
