So I bought Sashas FreeGift Extension without fully reading the description and now I need to modify it. I asked them for some assistance with getting this done and the only help they would provide is you need to modify the observer file and wouldn't elaborate anymore. I have tried editing the observer file with my limited PHP knowledge and keep ending up with 1 of 2 errors
Error 1: When adding any product to cart i get a 500 Internal Server Error
Error 2: I'm told by Magento "Theres not enough in stock of Freebie item, Stock Quantity is 3" (So this tells me that on trying to add to cart once it's trying to add the freebie item more then 3 times from a single add to cart click.)
Any help with this is greatly appreciated.
Ok so my problem:
User adds qualifying item to cart and gets 1 free gift. The user can add the qualifying item 20 times but he's only getting 1 free gift item.
What I want:
When user adds qualifying item to the cart 5 times he gets the free gift 5 times.
