>Do you just in your head have to tack on 10 to 20 percent (depending on the context)? Yes - and I actually prefer shopping at places that don't use manipulative ($x.99) pricing or if they do, at least tax has already been included in the price (a local card shop does that). If something is $0.99 I should be able to buy it if I only have $1.00 with me, but after tax it comes out to $1.08. Infuriating. I just tack 10% onto everything mentally, actual rate is 8.25% but 10% is easier to do mentally.
