I think I might try this!

I looked into this once, too and decided that I didn't want to pay for a subscription.  I do all of the things this service promises to do anyway, and I'm not going to run all over town to go to supermarkets that I don't normally shop at (and spend an hour trying to find the soup or something.)  I have two main grocery stores I shop at and I can get in and out in about 20 minutes (without lines backed up at the cashier) and get a week's worth of shopping done because I know the store layout and where everything is.  I think it would be GREAT for someone who lived in a large city where lots of sales are going on and for someone who has the time (and energy) to shop at a large variety of stores.  You'll have to let us know if you like it!

 Considering everything you have told me I am officially NOT going to try this, lol.  I don't have time for going to a gazillion stores either, lol, I spend enough time in the couple of stores that I already HAVE to go to.  Thanks for letting me know!
