I typically combine shopping with turkey buying using my purchase to defray the turkey costs. I then donate the turkey to a food bank. This year, the best deal I've seen is QFC's which I think was a $30 grocery buy coupled with a $0.49/lb turkey offer. Safeway offers a similar sliding scale deal but the grocery buy ranged up to $150.
Has anyone seen a better deal than QFCs? I'd probably go no further afield than Burien since White Center Food Bank is close by.
