Ok pottery, terrible customer service
My parents bought my wife a butter dish before Christmas, which we wanted to exchange for a half dish. Although initially receptive, once the person I was speaking to (Tadek) noted that we were just outside the refund period (on 3rd Jan!) I got a blunt response saying there was nothing they could do. I emailed back asking if they had any sort of policy concerning gifts bought for Christmas. No response. Two polite follow up emails sent received no response. The lack of engagement is as unpleasant as the inflexible adherence to their policy (which at least on one level might be justified - mean and unfriendly though it is).
In short, nice pottery, really terrible customer service. I would suggest not buying anyone gifts from the site - if the recipient doesn't like them, you're stuffed (unless you leave it to the last minute to remain inside the refund period I suppose).
