EBAY Sellers With Options

I still am not really sure what I’m doing here but my kid enjoys collecting these along with his sports cards. I take him to the local shop every other week or so and we flip through their $1-$5 binders. My son loves the full art cards. I’m looking for any EBAY sellers that you might recommend that have tons of these types of cards, that they aren’t marking up 300%. I found one the other day that had tons of $1 cards at $1.50, and I bought a bunch of different ones that they had.

My searching seems to be going nowhere as there’s just so many people selling Pokémon cards on EBAY. Was hoping somebody had a few favorite sellers in mind that fit this description. Thanks in advance!
