Wrong, you can easily sear a steak, just take the center section out & put the grate on the bottom section right over the charcoal.On seasonal items like BBQ's, local Walmarts (perhaps others too) can decide to just sell their last few remaining items off at steep discounts rather than store them for another year. You can get some killer deals this way. But they don't last long, and they're decided store-by-store so you won't see them on walmart.com Hence web spiders like Brickseek or GoogleShopping won't report them. $215 is considerably less than half price. If you have any interest in it, I doubt you'll see that price again for a long time.
WSM is more efficient...it could save you $5 of charcoal per cook...but it can't sear a steak either.
