WorldPay - For the bigger transactions. Although I dont like them much, they make me wait 8 weeks after payment is made for the the funds to reach my bank (apparently I am in a high risk industry). Also they are quite expensive.
PayPal - For small / ebay sales.
2CheckOut - When selling products on my websites.
Cheque - usually for services over £1k
Card Terminal - for if I am with a client in person.
Cash - If I know the someone well
