We participate in Oregon State's WIC program. Part of out WIC checks are for 36 ounces of different approved cereals, one of them being Kix. 18 ounce Kix cereal are buy two (36 ounces total) get one free. This DOES include WIC, as long as you scan your Safeway club card with your purchase.
Just a heads up in case others can benefit from this as well.
By the way, when you use your Safeway card regularly for WIC checks, whether you hit a super deal like this or not, you're helping others benefit from the program. By using less money yourself, more is left out there for other families or for new benefits in the future (like Oregon supposedly getting fresh produce added to the checks in 2009).
