I've heard of people having trouble getting refunds for returned items to third party sellers on Amazon but I just had one with Walmart. I ordered and returned a blood pressure cuff from a seller I didn't realize was a third party seller on Walmart. When no refund was forthcoming I disputed the VISA charge only to be denied and told by Walmart I had to contact the third party seller. Lucky that I had documentation showing they got the item back through Fed Ex and when I called them, was told they'd credit my account. I'm not sure why they didn't notify Walmart where my money went originally? Hoping to see the money soon on my VISA statement.
