Last year during BF I was going to put a digital camera on layaway, but after seeing the line literally wrapped around the store (evidently people were shopping and had their shopping buddy already in the layaway line), I quickly decided it was not worth the hassle and went ahead and scurried to the closest cashier and bought it.
I've only used layaway once before, and that time when I went to pick up my stuff, it took over an hour to get it! B/c evidently they lock the stuff in trailers and only certain people have access to unlock it, but those people were nowhere to be found!
But I still shop and Walmart and will continue to do so, regardless of the layaway.
