YOUR CREDIT CARD OUTLET

what is the cheapest option for a merchant to accept credit card payments?

i am a merchant and i already have a cardnet (from LLOYDS TSB in the UK) to accept card payments. However, i rarely use the machine as sales are normally paid through cheque by our customers. the charges are, i find, very expensive. are there any cheaper options for me available? i know of paypal but does paypal only work over the internet? how about if i want to accept payment over the phone? are there any other cheaper alternatives you know of? thanks

paypal.
