The best feature to accompany the challenges was the presence of a "Add To Watch List" button that accompanied the challenges. So, if you saw a card that interested you, you could put it on your watchlist, and add it to your cart and check out with it at a later date. Easy, and something I did way too often. One thing that I'd do it with was interesting autographs. Another thing I'd do it for cards where an obvious nickname was on the card instead of their real name. I only did that with 3 cards, but that was still part of my 100+ card order.
With another 40 misc cards or so still on the way from a second go through.
And another dozen or so still in inventory from an unexpected $40.00 daily bonus.
But hey, at least now I've got the Ron Darling auto from 2013 Archives on the way.
Back on topic, cards with nicknames:
not for something good.
So, 3 more card escape the COMC box, on their way to binder homes. Let's see. I've only got ... a lot ... more to go.
