There are more than a few free Dreamweaver Extensions that
can do this, provide a free shopping cart and payment system
through PayPal.
BTW--do you have a merchant account? If so, why on earth
would you, or anyone else, pay (about) 5% of your on-line sales
revenue when your credit card processor will charge you 1-some
percent plus 20-some cents per transaction? That's five times the
cost!! On a $100 transaction, the costs for Paypal are an
additional $4 per $100. That doesn't sound like a lot, but multiply
that by a thousand, tens of thousands, more? and it adds up.
If you do have a merchant account, talk to your credit card
processor, make sure they work with your host provider, and if they
do not work with your credit card processor, find a host provider
that does. Your credit card processor will fall all over themselves
to help you. They may go so far as to help you developing the code
you need to "get online." That's how desperate banks are to get
money, right now.
Even credit card processors will overcharge for internet
sales, but if you're savvy enough, you can circumvent all that by
typing in the sales information in your keypad just before you send
the order to the customer. The costs will be little more than if
the person appeared, in person, at your store, but you will
circumvent even the monthly charges your credit card processor will
charge if you're smart.
