<p>[QUOTE=&quot;Troodon, post: 26544060, member: 4626&quot;]Well it would avoid legal trouble and customer complaints, and it would at worst cost them 4 cents per cash transaction (assuming all ending digits have equal chance of coming up, it would cost on average about *2 cents per cash transaction), so seems like a good idea in the long run.</p><p><br /></p><p>It might not hurt for the federal government to issue some guidance, maybe even get Congress to pass something at a national level, to avoid the legal hassles a lot of state/city/local laws have about such things.&nbsp; But so far it seems retailers are adapting just fine even absent such assistance and/or guidance.</p><p><br /></p><p>*P.S. I&#039;ve not done the math, but here&#039;s a story problem for you: assuming all digits from 0 to 9 have equal chance of coming up, and a retail always chooses to round in the customer&#039;s favor to the nearest nickel to give change, what&#039;s the average cost of doing so per cash transaction?&nbsp; I&#039;ll assist in the set up here:</p><p>If the change they need to give ends in...</p><p>0 or 5: costs 0.00</p><p>1 or 6: costs 0.04</p><p>2 or 7: costs 0.03</p><p>3 or 8: costs 0.02</p><p>4 or 9: costs 0.01</p><p>Good luck and show your work lol.&nbsp; It&#039;s been a long time since I&#039;ve done statistics, but I came up with an average of $0.02 per cash transaction, assuming every digit has an equal chance of showing up.&nbsp; That&#039;s less per transaction than it costs most retailers to process credit or debit cards; I think they&#039;ll be OK.[/QUOTE]</p><p><br /></p>
