Free Iams dog food at Target?

There is a coupon for $3 off Iams dog food in today's P&G newspaper insert. It does not exclude trial size bags. You should hopefully be able to get a trial size bag for free at Target with this coupon!

Iams trial size bag, $3
--$3/1 (1/29 P&G)
FREE after coupon!

*Not all Target stores carry this size, but hopefully you can find it!

Thanks, Totally Target!
