Oh year I did a train on all my local wal-marts.lol I got pretty much all the good cards. Never had luck with blaster boxs the best I ever pulled was #d cards.lol
I was just looking for someplace that sold singles!
I actually have ordered the cards off a website. toywiz.com is the site I have used. You can actually get the cards at Wal-Mart. If you can, pick-up the booster sets they sell. It's about $15 for one. If they only have the individual packs for sale, feel the pack to see if some are thicker than others, there is a good reason to why those are.
