For a little bit of your time, you can usually get some high value coupons or FREE product coupons by writing to food companies of your choice.
These are who I wrote to last month and what I got in return:
Johnsonville Sausage- 2 $1 off coupons for any 1 sausage
Plum Organics- try one product on us for free (we get the fruit snacks at BRU)
Van's Waffles- Free box of waffles (saved me about $4-expensive little waffles)
Earthbound Organic Farm- $1.50 off pre-packaged salad
Pilgrim's Pride- $1 off any product (using this to buy E her mickey mouse nuggets at Target)
Organic Valley- $1.50 off any size milk (which made for some cheap milk 2 weeks ago)
Some companies will only mail you coupons 1x per year but for 10 minutes of your time, you might be able to save a couple of dollars. Most big companies (Heinz, Kraft, General Mills) usually write be back and say they don't mail coupons but be on the lookout for ones in your paper. I gave up on those last year but I might try 'em again to see what happens.
And if you get something and don't like it, write to the company and explain your dissatisfaction. They might throw in something for you in return :)
