Just out of interest, who has changed their use of plastic bags?

I know its not going to be popular, but I very seldom reuse the plastic bags from the supermarket. I use them as rubbish bags, and for storing stuff, but that's about it. The same as I did before the changes, just that my rubbish is held in a bullet proof heavy duty bag now instead of the lighter bags it used to be. Every now and then I go to a supermarket that has the lighter bio-degradeable type, so at least I know the rubbish bag will eventually decompose.

Its not as if I am building up a stockpile of spare bages or 'losing them' either. My behavior has not changed, and I am sure I am wasting more plastic than I used to.

Should I bite the bullet and buy bin liner bags and save the planet?

Maybe I should just keep going back to the place that has the bio bags? I would feel better and at least it should be better.

Anyone else out there as lazy as I am?
