I do the same thing! I don't want the hassle and wait time of an auction so I do fixed price BIN. It's so easy too. I just recently started including the receipt and that has really made a difference.I sell on eBay all the time but through fixed price with BIN as opposed to auction. In the description listing, I make sure to bold and underline immediate payment only. I have better success that way and usually sell items within couple days of listing. I tend to include receipt which of course increased probability of sale. Good luck on your sales!
eBay definitely seems to be the best way get the most for your money, if done right. I sold a wallet in less than 10 minutes for $300 that a consignment store offered me $175 to buy. The same for a key holder and a Prada handbag.
I think eBay users don't mind a seller who has lower feedback (I have like 78 on eBay) if they are someone who appears to be selling from their personal collection. I feel like buyers are OK with my lower feedback because they can check my history and see I sell Manolos, Jimmy Choos, Louboutains, LV, Prada, etc. every few months and realize that it's all from my personal collections rotating items in/out.
