I've added 2Co as a payment option, alongside paypal, My products are listed and sold in GB Pound Sterling.
I was delighted to see that I had a few 2CO sales overnight (my first ones!) but then I see the transactions are in USD! With the current exchange rate this means they have sold at half-price.. aaaargh
The currency code is set to GBP and works perfectly for Paypal transactions.
HELP!!!!
