From Canada. Bought vintage Pokémon cards in "near mint" condition, but only about 10% were actually near mint in my opinion. 90% had lots of scratches on the holofoil and should be classified anywhere from lightly to heavily played. I was not satisfied with the quality of the cards and called T&T customer service. They told me they would give me a full refund for the cards I wasn't satisfied with if I filled in the form on their website, and would even cover return shipping if I included a shipping receipt. They seemed pretty lax on returns, probably because a lot of people complained about this before, since most people don't read their condition guidelines, which has a rather low standard for near mint cards. So I sent back the cards... without tracking, because I figured I would be nice to save them money since they were going to cover return shipping. The courier told me it should arrive in a month, but I waited for 2 months. No refund. So I called T&T customer service again 3 times within a week but nobody picked up. I ended up sending an email to which they responded, telling me they haven't received my package. But 2 weeks after that I did get a full refund as promised, so I guess the courier was just delayed. Moral of the story is to include tracking.
TLDR: My purchase experience was full of ups and downs but ended up being fine as I got a few cards I wanted at near mint condition at a decent price, but as a collector I would not bother with T&T again as there are too many things that can go wrong and the hassle was probably not worth it.
