Third Party Sellers on Amazon

Need some new paper towels. Searched on Amazon. The cheapest was from a third party seller. He only had one review. But since he was the cheapest, I gave him a try. The shipment came. They were the wrong type of paper towels.

Amazon did not let me get a refund or return on this order through their web site. So I called Amazon. They contacted the seller, who said he would work on a replacement ASAP. When I inquired when exactly that would be, they said one week.

I am now not too confident in this seller. Luckily Amazon has a A-to-Z guarantee. I might be making use of that guarantee to get a refund if I get the run around from this seller.
