How many reusable shopping bags does a person need?

I prefer the handles on the Envirosax, but both these bags tend to develop a funky smell when stored away. It's probably the material they are made of.

I now prefer this Japanese range, Kurochiku. They don't feel quite as sturdy, especially compared to the Envirosax, but the dimensions are better designed, and the prints prettier.

They are quite inexpensive too, so I ended up with one of each size! Initially I bought the small in the chrysanthemum print and the large in the rabbit print. Then they introduced the one with the different handles and an inner pocket, so I got that in the print with the various flowers against a black background. I really like the turquoise print too.

Then there's the really expensive ROO brand. Very sturdy, with a zip pocket on one side.

This is a little one that's good for books, CDs and other small items. The bigger ones are expensive and I haven't found a design I really like.

This one I think is an excellent buy. It folds into its outer pocket. I saw something similar at Muji for quite a bit more $, and perhaps not quite as well made.

I think AB&C (found inside Kino, Raffles City basement, Taka B1 and Bugis Junction) has the biggest range of reusable shopping bags now, with new brands and designs coming in all the time. I really like the Miffy range they stock too. (Speaking of which, I have a Hello Kitty one I bought years ago - not sure where it is now.)
