I'll take 2 slots please.
Just a suggestion...You might want to break up the Giveaway cards into 2 gropus. The cards fro Boxes 1-3 and 4-6.
This would make for a price break and make those 2 spots "winners" as soon as they are pulled. You wouldn't need to ship the cards just PM the codes, unless the person that won they had another lot too.
Just an FYI
