For my neighborhood we do NOT get these ads in our Tuesday mail. I had no idea some of these store exsisted, so I was very excited to find out they had printable weekly ads! Not all Walmarts will take ads printed off your computer, but I haven't had any problems with them.
Glazier's Food Market Place
Los Compadres (click on "Especiales")
Smart and Final (click on "Store Savings")
These will be added to the price matching list I post weekly. Let me know if there are any other online ads that I am missing!
