Ebay flipping is a bit of a talent -- you've gotta live in the right place, and time the further discounts just right.
I've gotta add that you have to know your market too. If I am trying to flip a specialty brand (eg. Belvest, Corneliani, etc...) I often make an offer here first, to avoid Ebay fees. And you need to be aware of what sells and what doesn't. Some things are obvious. A white or pale blue Borrelli double button cuff is a sure thing, a peach shirt, not so much. Some things you have to have an eye for. My basic premise is that if I wouldn't personally recommend it, I generally wouldn't sell it. Therefore, Distressed laceups (btw, Johnnynorman, you poached those Varvatos from me, you rascal) will sell much better than shiny boots, textured casual jackets better than long, smooth finish coats, and so on. And so brands, although pretty decent, never do well: Schneiders comes immediately to mind.
