You get more sales when you accept cards. Chargebacks are a cost of doing business, and your pricing has to take that into account. If you get more chargebacks than is typical, you're probably offering a product or service that attracts the wrong kind of customer, and your processor might cut you off anyway. You probably shouldn't avoid accepting cards just because you assume you'll get too many chargebacks. You can accept cards to begin with, then refuse to do so if they don't work out for you.
