I'd be careful about putting biz cards on your bags. The cards are going to get crumpled quickly, will tear off the bags and the shabby looks of the bags will denigrate the value of your baits. You've already got good looking bags (I've seen them). Pass the business cards out to your fishing buddies, family and friends. I'd also put one or two in with the invoice whenever you mail bags out. You will go through 250 cards really fast. Just my opinion.
