We believe it to be about 150,000. You can still add cards to your wantlist, but not a bunch at one time with only a click or three. I have over 246,000 on my wantlist, but I added a bunch of those 1 at a time or using a person or team page to add more cards 1 click at a time.
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.
