Big mistake. Not offering credit cards will tell me you're an amateur or a company that fears chargebacks.

"We accept cash or check only". HA HA really? Sorry, I'm going elsewhere. Companies who fear chargebacks are often unscrupulous and demand "cash only" so disgruntled customer's can't come back and dispute.

I can't imagine running any business without credit cards ... doing so would be taking a giant leap backwards.
