Not all E90 Youngs have background shading like the examples posted earlier in this thread. For example, assuming PSA didn't slab a reprint:

It wouldn't take a whole lot of editing to fix the horrible picture used in the Ebay listing to make it look pretty good. I also wonder why anyone would make a misregistered reprint, that seems a little too sneaky (though not impossible - bring on the scans of the misregistered reprints!!). The 0 feedback score is worrisome, but with a 14-day return policy you can mail one of these to PSA or SGC and know before the 14 days are up if you need to start your return through Ebay.
I should add that I don't have any e95s/e90s so take the above with a grain of salt.
