We've bought two lots of tee-shirts for our family (mum, dad, one teen), using the "10 shirts for $50" deal that is on every day. Our most recent order included shirts for an event occurring one week after the shirts' arrival, and unfortunately one was the wrong size. I alerted 6DollarShirts and they apologised and sent a replacement straight away. We won't get our geeky shirts from anywhere else.
