That would be inflationary as almost every vendor will round up to the nearest five cents, not down.
Do you really see the price of ANY consumer goods ever coming down again?
Maybe gasoline? Heating Oil?
Drill, Baby! DRILL! :)
Canada had an interesting approach to this. Cash transactions are rounded up or down to the nearest $.05, but electronic transaction are reported to the cent.
If always rounded up, it is estimated it would cost consumers 3.7 M.
I suggest denominations of 1,2,6 & 7 be rounded down with denominations of 4,5,8, & 9 be rounded up.
85% of transactions outside the hood are via CC/Debit and need no rounding up. Give an Nickel, Take a Nickel appears. Nothing left that even costs .50 cents below the counter. My stint in retail, Even in the 1990s we did not bother counting out drawers to the penny, we dumped them and pulled a rack of 100 for the setup unless it was apparent that they went +/- 300 pennies and ate into the margin of fat/short 3 dollars. 3 weeks after pennies are gone, we will be talking dollar and 5 dollar coins.
Unless you are paying with a card. Those things will eat pennies like nothin’.
It’s a way to move us to a cashless society.
