I don't know if this is the right place to put this thread but I was wondering if some of you would be willing to tell me which reusable bags you recommend. There seems to be a ton of options out there and I don't know which ones are worth buying and which ones aren't. I'm looking for bags that are reasonable big and sturdy. I would like to know anything you have to say about them: the brand you recommend, the material, links? etc.
