I haven't purchased from them, but those vouchers are everywhere. So that gives you an idea of what they think the wines are really worth. I've read very mixed reviews - most very similar to what @Stressbaby posted. Some good, some you spit out. On average $8-12/bottle retail. Not much of a bargain, but probably not a rip off either, if you're getting the discounts. One advantage is it'll open you up to wines you can't get at your local store.
