Our store has been up and running for about 9 months now, so far so good. However, this morning we received an order with a sub-total of $109.22, a shipping charge of $10.57, and it lists a total of $124.90 (even after a long weekend, i can see that this total is incorrect, and should be $119.79) This leaves a difference of $5.11, which is not the price of any items in our store.
We haven't noticed this on and past orders, and the few that we've received after this order appear correct. These is nothing "unusual" about this order, it uses a common shipping method, payment method, etc. no discounts to calculate, no sales tax to consider. i'd like to chalk this up to just a fluke, but i don't like the idea of having to review each order to ensure the total is correct.
i've searched the forums and found tons of threads about incorrect tax calcs, etc, but couldn't find anything on a random subtotal/total issue. i suppose this question is directed more toward the forum gurus, does anyone know of anything i should check to investigate this issue, or just wait to see if this repeats? the more i think about what possible causes there could be, the more i come back to thinking "why would it work for every other order, but not this one".
thanks in advance..
