It’s alright, but could be better.

If you add Item A as a free gift and the customer wants to add that item to their cart (let’s say they want to buy 2 and get the 1 free) the plugin won’t work properly. There’s also no option to customize the alignment or font style of the default message boxes that show in-cart, so the styling will be all off. Overall, it’s an ok plugin that could definitely use work.
