If its 1 of 1 and the new seller is only looking for 230 then isnt it better to wait and see how quickly it sells? Especially since the buyer of your sale 1 is the same person reselling for 230 so they didnt value the trade to be that high.

The combined BO of the two hats it sold for was only 220:

Plus when he resold it, he had a buyout of 190 when he sold it for the bomber:

This is going to be too high

[edit]

Since you're using this for the bomber, you can just use the first sale to make this 220 flat, unless you want to investigate the tossle sale, but since the BO was 230 there if I understood correctly, it should be close anyway
