Definitely worth it, but Buy In Bulk!!!
Overall, I was incredibly satisfied with my order. I got 1200 near mint and 1000 played condition cards in the hope of having a higher chance at getting some older cards. While there were some played cards that had some damage to the corners or front, by and large I wasn't sure where the near mint cards ended and the played cards started. I got between 400-500 cards from Base Set, Base Set 2, Jungle, Fossil, Team Rocket, Gym Heros and Gym Challenge. Nice! I only got a handful of Neo Era cards and only 1 E series card, but I got a fair number of cards from most expansions after and including ex Crystal Guardians. I did get about 400 cards from Hidden Fates (I placed my order right before Cosmic Eclipse came out), which were all in a big lump with duplicates of 20+ for any cards and was a little disappointing at first. That is why I would highly suggest you buy in bulk. That lump was what I went through first, and I would have had a very sad opening if I had only gotten those cards. In any case, the rest of the lot was fantastic and more than made up for it. Some highlights and things to note: I got somewhere about 300 trainers, so 12.5% of the order. I got (I think) 7 first edition cards, where half were trainers, but I also got a fossil Kabuto, Jungle Pikachu, and a Koga's Tangela in first edition. I got one shadowless card (charmander), so this may not be a good place to hunt for shadowless cards. I also got 3 Japanese trainers from the Gym Heros set (cool for me, because I've never had japanese cards), 1 Spanish card (jungle Mankey), and 1 French (I think) card (neo genesis Piloswine). As someone who hasn't collected cards since the ex Dragon expansion, I found this to be an awesome way to get a few of the cards I was missing in the oldest sets (one day I will get that fossil Cloyster!) and replace some of my childhood cards that weren't in so great shape with nicer ones, while also starting to build up a collection of what's come out since then.
