When you are on a set's page and click Collection Summary you get a list of options. Click on Add Multiples. It will list 25 cards at a time and you can add up to 10 copies for all 25 cards at once. Make sure to use the drop-down at the top of the card list to send the cards to the right place AND make sure you add that page of cards from the button at the bottom of the list before moving to the next 25 cards. It's saved me a ton of time since I found that option.
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.
