Often seems to be the case in B&S that what sounds like a good item unsold is unsold because the seller's communication is terrible. There's been a few times when sellers have just failed to get back to me, or have terrible photos (or photos that don't show some aspect of the item) and don't get proper photos up, or whatever. I've made a few good purchases off B&S (including the suit I'm wearing today and a couple of my favourite sports coats) and encountered some great sellers even when I haven't ended up buying due to sizing issues or someone else getting in first, but some sellers just don't seem to want to sell.
It'll be great once it's possible to search B&S by size. I keep an eye on new listings and occasionally on bumps but trying to actually search listings is a fool's errand and with all the bumps going on if you don't keep an eye on new listings you'll never see new items come in because they'll be buried under all the bumps.
