Anyone know where I can get a wheely carrier for my shopping that doesn't make me look like an old granny?

I decided to change from a Platypus bottle to a Sigg bottle because I was worried about horrible chemicals, like phthalates, leaking into my drinking water. Someone was telling me that the inner coating of Sigg bottles is similar to plastic (no idea if that's true) and that I should get a Klean Kanteen instead. Anyone know where they're sold in London?

hi...i'm trying to be green with my christmas shopping...anyone have any good suggestions for green presents?
