Lisa got a derned good deal on those... All the grocery panniers I looked at were priced individually, and my Jandds were $55 each.

I've not had good luck with Nashbar panniers, either. I didn't get the groceryones, but back when I was starting out with the commuting thing about a year ago I bought a set of their DayTripper saddlebags. First of all, they're pretty small as panniers go. They didn't have hooks to connect them to the rack, but came as a single set that folded over the rack (sort of like the saddlebags in the old cowboy movies) and sort of held on. I replaced them with another set in pretty short order, and they've been in the "spares" box ever since. I buy a lot of stuff from Nashbar, but not panniers any more...
