Storage, storage, storage. You can never have enough storage. Especially versatile, multipurpose storage, like the Pia canvas carryall. It doesn't scream the name of some supermarket and it has a nice design.
Plus, it doubles as a storage solution. I must admit I can be kind of messy sometimes. If I don't have a place to put things like books and magazines, they'll pile up in some unsightly manner in a corner of my apartment. So in addition to being good for hauling your groceries, this bag is a nice solution for your reading materials or DVDs or what-have-you. Plus it doubles as a reusable grocery sack. The small version is £15 and the larger is £23. You can't really lose here, because you're being environmentally conscious, and you're organising your crap. [MilkDesign via BLTD]
