i buy from where ever. If it looks good and helpful i buy. I would suggest going internet. it is the cheepest way to sell something. you could also talk to admin about how to get a banner at the bottom of the posts where there are different ads. just a suggestion. I would also do coupons or deals on your books. that is a huge thing for me. I don't pay full price for anything i don't have to. and if i have to pay full price I have to really think about the purchase because we are on a limited budget.
