Very interesting to check out how different POS systems handle the rounding!

I share GP's assumption, assuming that businesses would re-price based on the final cost. There is a financial incentive to get the transaction to round up, and financial incentives are usually pretty motivating.

(Given the max incentive is 5 cents per transaction, I might guess a focus on one-off transactions like a bag of chips, vs. the complexity of attempting to get the average grocery bill to end in the right #!)

Would be interesting to see if the after-tax prices of potential single items (chips, water, pop) changed with this rule. Anything that was 99 cents, now that HST is 13%, comes to 111.8 cents, rounds to 110 cents. Bumping that to 100 cents even, rounds to 113, rounds up to 115. Profit of 5 cents on '99c/1$' item for 5% difference. Hard margins to give up!
