I'm with Toadling, Brian, et al in the "buying a bag of carrots is an actionable item, why not use OmniFocus?" camp. I haven't seen anything mentioned in the discussions of purpose-built grocery shopping tools that would make me think it would be worth buying another app (and having my tasks split betwixt the two). YMMV.

I've got a Grocery Shopping SAL that has my staple items set up as repeating actions with the repeat interval set to reflect the usual consumption rate. I have a hierarchical Errands context with a number of contexts for various stores where I might prefer to obtain certain items, and a catch-all Errands:Grocery store context where I would put the bulk of the items. If I decide in my menu planning for the week that I'm going to make something using a non-staple ingredient, or unusual quantity, that gets tossed in the appropriate context (and lives in the Cooking project). In any case, when I hit the store, OF has my shopping list ready and waiting for me.
