As a handmade clothing shop, the app is great for adding options and add-ons that cause price changes for a more customized product for your customers. However, when utilizing the price changes it creates a temporary new product for the customer and adds it to their cart with the changes and then doesn't deduct from the original product's inventory causing you to oversell when you are limited in inventory. Bad news for a shop that relies on stritct inventoy during new product drop days. Also because it creates a temporary product, you also lose out on potentially recovering sales by sending cart reminder emails because by the time your abandoned cart reminder email is scheduled to go to customer, the temporary product isn't in their cart anymore because its time sensitive. Besides these issues discussed, this app would be great but not for stores with high volume traffic on drop days with strict inventory unfortunately.
