We usually grocery shop together, doing one bigger trip a week, and then occasionally stopping individually if we only need a few items.
We always buy plenty of produce:
A few kinds of cheese (usually one shredded, a block, and blue ... for the man of the house):
We make sure we always have breakfast staples on hand:
We grab any random items that we're out of (we love pickles):
And any special ingredients we need for meals we're cooking:
Sometimes, if we're feeling sassy, we buy a little snacky item, or something new to try.
Everything gets crossed off of the list, and whatever we didn't get or couldn't find goes onto a new list on the fridge ... for next time.
Who does the grocery shopping in your home?
How often do you go? What are your typical purchases?
