OB Ultra Tampons 40 count box

In case you haven't heard, OB is discontinuing there Ultra Tampons and these babies are selling for $40ish a box on ebay. I scored this box at my local rite aid for $6, ebay fees cost me $5, Paypal fees of $1.40, and shipping of $2.50 and I sold it for $38, so a profit of $23.10. All the fees are why I'm so reluctant to sell anything on ebay anymore, but there is no way I would make a profit like that any where else.
