Within 5 minutes of placing my order, I asked Tennis Express to cancel the order as I did not realize its free shipping did not include products over 7 pounds. The customer service rep stated that tennis balls did not simply fly to my home, so they charged for shipping them (I didn't think things under 7# did either, but...). I again asked to cancel the order. The only response was an automated email saying they would respond. They didn't. Instead, after a day, they sent me an "order shipped" notice.
