Sounds like you’ve had Bagnesia (you know- like amnesia with reusable bags). Luckily, there’s a solution for your problem- the Bagnesia Reminder Kit. Not only does it come with it’s own bag (kind of similar to the envirosax but easier to put the elastic band around instead of snapping the button) it also comes with reminders to help you remember to take them from the house to the car and into the store with you. Problem solved! http://www.bagnesia.com

I have a few of the flip and tumble bags and I use them all the time. I usually have one in my back pocket (it compacts down to a size smaller than my wallet). It is amazing how many times I used plastic bags in the past. I also bought a ton for gifts last year and I have only received glowing responses. I also think they are much better designed than the other bags out there (that rarely get used). I have a lot of those as well and always forget them. The flip and tumble bags are so easy to remember.

I am partial to the GreenAid because it comes on a hip, little ball, as well (that looks like a grenade), but it has a clip so you can put it on your keychain(!) I always forget the other bags…
