Cart specials app

This app automatically adds a "Buy 4, Get 1 Free" promotion to your store, giving customers a discount on the cheapest item when they add four products to their cart. The promotion works in real time, counting eligible items as shoppers browse and automatically marking the cheapest product as free for every group of four. When customers buy 8 products, they'll get 2 of the cheapest items free. This automatic discount applies at checkout, encouraging customers to add more items and increase your average order value.
