[ic] Authorizenet question?

[Scott Martin]

Hi

Just the other day we had a credit card processing company salesman at 
our office. We currently take cards over the phone and asked him if they 
  do e commerce applications. He tells me they offer authorize.net & I 
need software at a cost of approx $ 500.00 US.

Is this something I really need or does the perl module take care of it?

Very new to all this but appreciate any suggestions, alternatives etc.

Thanks
Scott Martin
