IntlOrange,
I think I have a setup which may interest you. However, this would (currently) require you to have your iPhone connecting to your Mac, with the OmniFocus webserver running. HOWEVER, don't fret as this will work even better with the iPhone app when it comes out.

1. Create a PROJECT called Shopping List (or whatever you like).
2. Make the project parallel.
3. Create a child item entitled CLICK HERE TO CHECK ALL.
4. Now start adding your items as child items under CLICK HERE TO CHECK ALL. I actually have mine added in the order of where they are in the store, so I don't have to backtrack to get an item.
5. What I've done at this point, is added each item I need under this project. This becomes a PERPETUAL list for me, and I add items to it as I need them if they havne't been documented before. So, although i don't need mustard every week, it's added anyway.

...stay with me...

Now I have this MASTER list of grocery items. I click the box for CLICK HERE TO CHECK ALL so all items are checked. Then, i UNCHECK the items I need.

With the iPhone webserver, I now get a list of needed items (by not having a check mark). As I walk through the grocery store, I check 'em off, and when I get home all the items are checked off on my Mac as well (due to the webserver).

Then I start the whole process over again by checking all items and UNCHECKING the ones I need. I may realize on Wednesday that we need bread, so I'll uncheck it. Then, before my wife and i go shopping we sit down and I go through all the items ("...do we need bread?" "Yes", "...do we need soup?" Yes. The each item gets unchecked and shows up in my view as uncomplete tasks.

Now, when the iPhone app comes out, you won't have to worry about using the webserver, as all this should happen over the air, but hopefully you get the drift.

if you do not have your iPhone set up with the webserver, just google Omnifocus webserver and you should get a few forums regarding how to set it up. the only issue is you have to have your Mac on and awake for you to interact this way.

I'm sorry for the long post, but I wanted to make sure I explained this correctly. Thanks for your patience. :) I've attached a screenie.

P.S. Forgot that this can work as a standard printable list as well. Just change your view to "Remaining" and those items you have checked off won't appear. Then print.
