Why is my Selling Expense so high?

[Dale]

I have just started using the program.  I've entered in my stock and costs, my Expenses, and downloaded EBAY data.
After the first sale I got, everything looked good. However, when I entered the second sale, the selling expense went way up.

I did put in zero for the product cost (intentional), could this be an issue?

Hi,
Please check your Ad Fee column first, as it can be confusing.

Since ad fees are returned through the API at the LISTING level, and not at the TRANSACTION level, they will all be grouped into the first item that sells for that Listing.
So the totals should be correct, but that one listing may look very high.
Let me know if you have additional questions if that is the cause.
