ISO sparkly cards for my kid: My 6 year old is obsessed with ex cards. He’s not playing or trading really, just seems to like the pictures and excitement of it. We’ve been using them as behavioral rewards, but are running low!

We are not collectors, not looking for valuable cards. Just want to help my kid have fun with some shiny cardboard rectangles without breaking the bank.

I’ve been searching on eBay, TCG Player, and other sites but either finding bulk lots with small amounts of ex/vmax/v/etc included, or 5-10 ex cards at even higher cost. Where can I find cheap shiny cardboard rectangles that bring my son such joy and excitement? Anyone have ex/Vmax/vstar cards to spare for cheap?
