How would you handle things like change on a 1 dollar item with 10% sales tax? I use a dollar and a dime to pay for a coffee refill regularly, and no coins smaller than $0.25 would be messy without forcing prices to go up/down to round evenly or elminating all cash. Rounding to the nearest cent now isn't an issue since sales tax should always be roughly an integer percentage, but rounding to quarters is problematic.
