Pros: affordable, lightweight, durable
For months as I grocery shop I have been bringing my own shopping bag, but I still couldn't get away from the individual bags that you use to put your produce in. The cashiers get upset if you mix apples and oranges because they are different prices, and if you don't use a bag then they roll around and get bruised and lost.
This bag is awesome, it is very lightweight, so it doesn't add any weight to your produce, they are durable and kind of cute. At $2 a piece, it is easy to buy several to keep your produce separate and safe.
