Was pretty excited to get this going but there are a few flaws that made us uninstall just a day after installing.
#1 bummer - The pop up doesn't show up until the customer has already put the minimum amount needed for the freebie in their cart, so there is no upselling. There is no motivation for shoppers to buy more.
#2 bummer - the pop up forces the customer to pick a free item. Pop up won't go away until the customer picks something.
#3 bummer - If the customer uses a coupon or discount, the free item is still in their cart. For example, our gift started with a $25 purchase. Customer bought something for $25 and was shown the pop up window with their free item to choose. It was added to the cart, but then the customer used a $15 off coupon, and the free gift was still applied.
Great idea, but too many kinks. We uninstalled.
