Here's my experience with Tophatter as a buyer. My daughter and I have ordered several items from Tophatter. Love, Love, Love!
I researched their company before becoming a buyer about a year ago. I have gotten great deals and enjoyed the excitement of real time auctions. I have had only good experiences! I would recommend that before bidding and/ or buying, scroll down and click on the seller's name. You will be given payment options, which are PayPal (where you have an immediate safety net) or/and credit or debit cards. You are always able to ask questions. I always buy from US based sellers, as the overseas sellers take forever to deliver. I've gotten fantastic bargains. Tophatter does allow you to cancel a transaction within the first 20 minutes (approximately) after purchase. I say go for it! I know that we as consumers see complaints, but again, my experience has been fantastic. Best wishes!!!!!!
