There are Rachael Ray bags on QVC and Amazon but they're close to $30 for two without including the shipping. The ones I bought at Kroger and Jay C were around $3.00 each, they were made like regular reusable bags except they're insulated with zipper closures. I'm sure they don't compare to Rachael Ray but they worked well enough for the price.
I think they were $14.99 for a two pack at Costco. There was a huge one and also a lunch sized one. I had already put a bigger lunch sized one in my cart that was also the same price. I didn't want to go all the way to the front door to take it back so I bought it as well. They get a lot of use.
Wow, if they are the same ones I saw on QVC and Amazon that is an amazing price. But there's no Cosco around here. There's a Sam's Club about 50 miles away but I don't have a membership and never go there. I will checkout Cosco online but I often find shipping costs when ordering online is too much to be worth it.
