Evalon have just launched a terminal package through Costco, transaction costs are from 1.1% for credit cards, 11p for debit cards.
I will look into it as we are getting asked about card payments more and more.
As for cash banking charges, change your bank, use the post office for free banking, A & L, Co-op all allow banking through the post offices, much easier and a lot cheaper I even get interest on my A&L accounts
