DuPage Doubles Online Resale review for Add to cart button ‑ FoxCart

This app allows my customers to quickly add items to their cart. Our store has only 1-off items with very little descriptions, so there is really no need to drill into the product page. I also had a really good customer service experience with the dev team. When I noticed something wasn't working quite right they had it fixed within a day. If I could change one thing, it would be making the button disappear more quickly when an item is sold out (again with the whole 1-off thing). But, I think that's likely a Shopify issue, not an app issue...
