Hello. I live in Canada (Quebec to be more precise) and love GG.Deals. One thing I've noticed though is that it's not easy to tell when I see prices listed if the site selling the games charge taxes or not.
For example, at the moment, the Epic store has Spider-Man Remastered for 39.37$ CAD and they charge taxes, which comes up to a grand total of 45.25$. In comparison, GamersGate has the title for 41.99, but this is a price that already includes taxes, so it ends up being cheaper than buying from Epic. Since taxes calculations are a store-based attribute, perhaps taxes could automatically be calculated for sites that charge them, helping us Canadians figure out which price is actually cheaper 🙂
