Look at Air Canada when they post an online deal and miss a zero. They pull the deal down as soon as they find out, but honour the ones that were purchased.
While offering to split the difference is nice, at the end of the day the merchant is responsible for its software, and if you bill a client, the deal is done. Coming back later asking for more is bad taste IMO. Take the loss up with the company who designed your software, or the person who assigned the variables for cost.
