It's a great idea, Ameet. For the last year I have brought a different monster box to each show. High end base, then numbered, then RCs, then inserts, then vintage. Cards in soft sleeves are a quarter, Cards in top loaders are a dollar, unless marked. Nothing in any box over $4.00, and the boxes are always a hit. People build nice little piles, and you can move stuff quickly.
Glad to hear you're back in the zone and ready to kick it card-style!!
