Query: Bad Experience - Zero star rating

I have always had good experiences with Amazon.com until this purchase!Please,if you are to keep this vendor on your website, I would strongly suggest that ANY ITEM PURCHASED from this website THAT CANNOT BE RETURNED, have a CLEARLY STATED MESSAGE THAT THE ITEM CAN NOT BE RETURNED listed beside the item BEFORE SALES IS COMPLETED!All info on online said that this memory was the correct memory for my machine.I was EXTREMELY DISAPPOINTED to find out AFTER the memory didn't work in my computer that I couldn't return it!! Supposedly, in the fine print it was stated but I didn't see it when I made the purchase.
