There's signage for a few other deals going at Safeway:
Buy 3 GM cereal get a Cat for free NV bars (current ad period only I think).
Buy $25 Gortons products get $5 off (appears to be cumulative by the wording, when you hit $25 you get the $5 off). Goes 5/1-6/30/10 good on 5.75oz-24.5oz products.
Buy 4 Hamburger Helper get a Cat for $2 off gd beef + HH (might be another 4 I forgot to write that part down or get the dates). Best to use these Cats this week, while they are cheap, last time I let the thing expire because the reg. price was so high.
