I have a listing for a fixed price. The buyer and I came to an agreement, so I sent him an offer. Long story short, my math was wrong. I am off by $10, and cannot find any way to even look at the offer. Any help would be appreciated.
You should be able to access the offer via the item entry on your sold page (been so long since I had one I don't recall the wording or the location, but on the old My eBay Sold page it would be a "Review Offers" entry under the "More Actions" dropdown).
