I just signed up and was bombarded with Chef Boyardee, Kraft Mac/Cheese, Oscar Mayer injected/processed meats, etc.

I'm a price-sensitive Whole Foods and Trader Joe's shopper in Palo Alto/Mountain view and would love to have great sale notifications from these locations.

Also, most of my friends are the same way. Food at these locations is expensive and we aren't super wealthy so pricing is really painful sometimes.

Either way, great job. I love the site/app/idea and this space is ready for an idea like yours. Cheers!
