I am currently using Apollo hosting for $20/month and part of the deal is that you can get free (no fixed cost) credit card processing via Authnet for about 3.5% and $.50 per transaction (starter package - prices drop with volume). All this for $20/month.
I thought about PayPal, but my personal experience is that I like the security of a credit card and with PayPal the customer has to set up the account (if they don't have one) which could cause the lose of a sale.
All that being said, does any one have any hard data, guesses, anything regarding numbers / percentages of people that would prefer a credit card over paypal or vice versa? xx% of people are exclusive paypal while yy% are exclusively credit card, and zz% are indifferent...
Also, I have my site
