I LOVE this coupon!
Right now you can print a new coupon for $0.50 off any Muir Glen product .
This coupon gives you a great value at many different stores but if you have a store near you that doubles it usually leads to free or almost free tomato paste.
Near me we have this deal at Harris Teeter:
Muir Glen Tomato Paste (6 oz) $1.39
Use $0.50 off any Muir Glen product 
Final Price: $.39
Otherwise you should be able to find great prices at both Walmart and Target.
