I don't use grocery bags anymore for the main part of my groceries. I unload shopping cart onto self serve checkout shelf, scan everything and move it to the bagging area, then just put it all back in my cart. Then i go to an area where i'm not blocking anyone and load up the panniers and backpack (usually just the milk goes in backpack). The local giant food store has a bench that has worked nicely as a "load up station". I sometimes grab a quick meal sitting there too, helps me cool down and not shop hungry.

I will use 2 plasticgrocery bags for my rolls, but i avoid it if at all possible. The loaves are OK in a backpack, and i usually only get 2-3, but the packs of rolls are way too bulky (and they smush easily and stay smushed) to try and carry them all in a backpack or pannier. I plan to switch to my re-useable bags next time on, so this past shopping is the last time i use the plastic ones.
