Ordered a t-shirt from Threadless. It never turned up. They offered to refund me in full, no complaints needed. They also gave me a $5 voucher for future orders, bringing the whole deal even further into the red for them. This is pretty excellent customer service. I struggle to see this happening in the UK.
I grumbled to the nice folks at TripIt because I wasn’t eligible for their referral competition, so they sent me a T-shirt instead. So I think it’s only fair that I put in a good word for them: Try it. If you travel a lot it’s invaluable. It’s free. It’s better than Dopplr. Er… that’s it.
