Attribute Prices Show Different in Store than in Back Office

[Guest]

Somewhere between the attribute setup and the store front's item page, the attribute prices are coming up different.

I have 4 increasingly higher prices for an item. I have tried two ways but both are incorrect.

I have to item selling price at zero and then the 4 attributes with their full prices. None of these show correctly in the store.

A price of 22.34 shows as 21.78.

Then I set the base price in the item page at 22.34 and the first attribute price at zero. That then shows properly in the store.

But the other 3 are still wrong, even though the add-on price is correct in the back office.

I have no sales taxes or any other money related options anywhere, let alone any that would reduce the price.

Suggestions are welcome.

I have the same problem.
If I add an attribute the price shows up differently- slightly less -in the shop.

Any help would be appreciated!
