I went to one of their open houses. I was amazed at how many forms you had to fill out and how everything was all secure and secretive. We go through the whole thing and watch the video bla, bla. 2 things jump right out at you...first, is the $5000+ membership fee and second is the fact that you can't come back if you decide not to sign up that moment.
Anyway, me and my fiance were very interested seeing as we would be buying a place soon, however, we don't make much money and tend to look for good deals while shopping. I admit that we were really rash in our decision. After we left, I didn't feel 100% about it, and doing a quick search on the internet made me find that, despite potential savings, we would really have to spend A LOT of money in order to even get close to breaking even. Plus you can only shop there, from their catalogs, no refunds, no samples and the website is terrible.
Fortunatly, the state gives us 3 business days to cancel in writting and get a refund. They were nice, but they tried whatever they could, including making some rather dubious statments and guarantees that I know they couldn't keep, to try to make me stay.
Bottom line, Direct Buy DOES work if you spend a lot of money. If you are going to buy a house and redecorate the whole thing wall to wall, then you WILL save money, but for us, being on a tight budget and trying to save, it just becomes another expense that doesn't pay off.
Never EVER let someone make you sign anything without giving you at least a day or two to sleep on it.
