I purchased a lot of 100 food coupons for $1.98 on Ebay- I figured  for that price I would at least get my money back in savings. 

I got a $2.00 off of wheat thins or triscuits (both products I use) and a bunch for Campbells soup and other things which we use. YEA!  The rest I am going to offer on Freecycle.   As always with ebay, just make sure you're buying from someone with good feedback.  The woman I bought from mailed mine the next day.  I am now going to go look for non-food couons and do the same thing.
