I have two accounts in my home, and they have different pricing for both. Anyone know why?

It's a site bug. GOG does have CAD support + some regional pricing for Canada, so in whichever account doesn't let you select Canadian dollars (or seems to have bizarre prices), just place something in your cart and go to the checkout -- you don't have to actually pay. That should reset your account to your normal locale & chosen currency.

Edited because I flubbed a word.

Thanks. I see one of the accounts is set up for pricing in the US, the other Canada.

My advice should've read "place something in your cart and go to the checkout," by the way. In case that wasn't obvious. :P
