i had a few conversations this year with staff about how in uk we sell things at 99p or 6.99 - easy 1p change . they sell stuff at whatever $6.84, $10.47 - it always comes to so many cents over the dollar - result pockets of change and loads of added costs for them having to buy in extra change (to give to tourists).the staff just didnt get it!

take a water park, lots of people have wet dollars in their pockets, why not just set prices to whole dollars or 50 or 25 cents?? ,

still its fun for the kids , diving for lost change!!!
