http://www.eatbetteramerica.com/ has Muir Glen coupons.
It states $1.00 off any Muir Glen Product and it lets you print up to 10. (or it should- it let me)
I just found another site, http://www.thebestlife.com/ also has coupons for $1/1.
Fry's has Muir Glen organic tomato paste on sale 4/$3 - or .75c each. This is in the organic foods section, and it is not in the ad. These are the smaller cans, but you get them FREE and they owe you .25c.
If they are out of tomato paste then the BIG cans of the canned tomatoes were 2/$3 or $0.59 each after coupon, making them a good deal too. Think year supply soups and stews, people! :)
Because these don't have to be doubled, you can use all 10 or how ever many you want at a time.
