That's exactly what I said in my reply at the bottom of Page One. Try my method and you'll see that it works. Takes more time, but that's the only way to do it once you pass the threshold for mass-add. I've been doing it that way for years to keep adding the cards released for my teams and athletes since then. My wantlist is close to 250K as well right now and I still have more to add for all the cards that have come out this year that I don't have yet.
NO PWE's EVER!!! PLZ PM me 1st before sending any offer. ONLY selling cards as of March 2024. No trades or purchases right now.
