We have these racks too - they are fantastic. They used to be called Gorilla Racks, but the company was bought out and they are under a new name. Each shelf holds 1200 pounds I think (not that I'd ever have that much weight, but I believe that is what the box said - we bought 8 more sets in February). You can get a set from Costco for just under $60 I think. I love having a place to do my food storage now and hopefully one day it will look as great as Amy's and some of the other Savvy Shoppers out there.
Oh and I must have missed the sale on the individual applesauce....we love those so I'll have to watch the shopping lists closer. We really need a Buy Low or even a Winco up here in Layton!!!
They were at Walmart
