Thanks guys. I tried it today and I think I may need a trailer. I'm still not sure: gotta run it by the wife. What I did though, re: tsl's comment, is take off the pannier and place them in my cart. While being as conscious as I could be about weight I placed all of my items into the open panniers as I shopped so that I'd know I had the space, at least. Then a spot check for weight before I checked out was good. I just didn't get as much as I thought I would. And I may not be able to make it down there 4 days a week. We'll see. Thanks for the responses guys/gals! And thanks for the link derail, that one eluded me in my search last night.
