J'adore Baggu. I've featured them a couple times here on One Floor Up, I give Baggu bags as gifts to all my friends, and I use them at the grocery store all the time.
I just ordered the new Baggu Produce Bags. There is a small and large net bag to put your produce in, instead of the disposable bags that you usually use to group your apples together for weighting. I'm looking forward to putting them into action.
