I'm not sure that will really happen. I mean, there's still tax, and people paying by credit card/debit card/check, and the urge to price things at $0.99 instead of $1, or having 3 boxes of pasta for 1.50, or the fact that the cheese is $8/lb but you got 1/3 of a pound or whatever, which will result in odd numbers. So I don't think stores will bother adjusting the prices on the shelf. Maybe they'd adjust the total price you'd pay at the register -- but then, what a customer service nightmare to always be rounding up the total to the nearest dime (but only if paying by cash).
Case in point: when I was living in Israel 12 years ago, they'd recently gotten rid of the agora coin[1], so the smallest denomination was 5 agorot. Prices were listed as 4.23 or whatever, but at the register they'd round off. I don't remember being always upset at the rounding, so I think it was fair, but it's true that I don't remember it clearly.
So, while I understand the worry, I don't think that it would actually happen in practice.
[1] 100 agorot to 1 shekel; Wikipedia in their Israeli_new_shekel article says the 1 agora coin was withdrawn 19 years ago, but I seem to recall getting one in change on occasion, but most people didn't want to deal with them (and probably didn't have to from a legal standpoint).
