Retailers aren't naive to the fact they MUST adjust cost scale to maximize the opportunity to a round up situation or potentially face a loss of revenue.

Granted, the amounts may be seem trivial to the casual purchaser, but the business owner will certainly want to ensure as many pennies as possible find their way to the black side of the ledger.
