Free Gift in cart [Will Update with More Features]
This Section, Built into the Cart section lets you add free Products to the cart. You can use Price, Product ID, Variant ID, Sku, Type or Vendor as a criteria. You can then pick a Variant ID and how ever many of them you want to add to the cart.
At this time it can work one of 2 ways. Auto Add to cart (but you cant remove it, it will just re-add itself) or A Button to add it.
Updating: Currently Making the Button more Obvious. Plan on adding a Modal / Popup for it (optional), and a Select a Gift Option. Technically nothing in this says it needs to be free......
