It depends on exactly your situation, we bought into the sales pitch 3 years ago, paid $3k, this year was the first to "renew" @ $300. We thought about not renewing, but decided to give it one more year as we were planning on some major purchases. Bottom line:
bought a Stanley Furniture dining set, compared that price vs. the store prices and saved $5k ($12k at store, $7k at Direct Buy - including shipping). Bought a bedroom set for $2k, store was $3k. Bought snowblower for $750, store cost was $755 - yippee. Bought earrings for $150, with store cost around $250. Bought a couple of bookcases - actually ended up more expensive through Direct Buy - we didn't "shop" that one previously.
So we felt better about our "ripoff" as we had previously termed Direct Buy. If you're building a home or remodeling or major purchases then yes, you'll save money. We found electronics are a wash from purchases, the major savings are in furniture & jewelry.
Since we're probably not planning on purchasing anything major like that again, we'll probably drop it this year.
The negatives are most people want to feel / touch before buying - which you can do at stores and then purchase at Direct Buy. Rarely does the shipping go directly to your home, you have to go to Direct Buy to pick up, which means getting some guys to help, then the boxes...
We'd do it again, only because of the big purchases we knew were going to happen. We'd also love to have it if we ever built, but we're not going to, so there goes that!
