<p>[QUOTE=&quot;pk_boomer, post: 1098261, member: 23933&quot;]I&#039;m curious how a retailer (like Walmart for example) would do this, considering the infinite possible combinations of random items that a customer can have in their shopping cart. I would think that this would be nearly impossible mathematically to do this in a way that would ensure that more purchases are rounded up instead of down - and all for 2 cents per customer transaction? I&#039;m not trying to be argumentative, I&#039;m really just curious how that could be done. I&#039;ve heard this argument many times and I still don&#039;t quite understand it.</p><p><br /></p><p><br /></p><p><br /></p><p>It is still a competitive free market economy. Ultimately prices are still determined by supply and demand. If one retailer chooses to round a price up, that leaves the door open to their competitor to round it down. (Better yet, undercut the competition by more than just a nickel - but then that&#039;s how things work already.)</p><p>&nbsp;</p><p>I fail to see how rounding can possibly have any significant effect on the average customer. Think of how many transactions you conduct in cash every day - even if you average 10 transactions a day, and you are unlucky enough to have all of them go against you (one in a thousand chance of that), you lose 20 cents.</p><p><br /></p><p>It&#039;s interesting that you mention half-cents. Imagine that we had half-cents up until today, and that we were abolishing it. Would you really care that prices were going to be rounded up to the next whole cent? or that prices would now be in whole cents and not half cents? Like somebody already mentioned, gas prices have always been in tenths of a cent - so why aren&#039;t we upset that they round our gas purchases up the nearest whole cent?[/QUOTE]</p><p><br /></p>
