I was talking to a friend about this and we started talking on the lack of small change in most european countries. They can avoid small change because everything is priced at a rounding point. A hamburger costs 2 euros, not 1.99 + tax. Tax is already included in the price. But we came across the reason why it wouldn't work here. A company can't have a set price across the board because each country has a different sales tax rate. The only way for this to work would be for the companies to bear the whole burden of the tax and charge the same for a Big-Mac in LA (9.75% sales tax) and Salt Lake City (6% sales tax). I don't see this happening in the near future.
