If I ever take reusable bags, I'll take fabric bags - the plastic 'bags for life' are a complete con which they guilt trip you into buying because you've forgotten to bring the ones you bought last week - so instead of the small thin plastic carrier bags you end up with just as many large, thick bags which are more costly to make and cause more waste.

I agree with leeneia - there's a whole lot more money and resources being wasted on other things.

And Mr Happy is dead right :"I argued how's it protecting the environment if the bags are still being manufactured & sold ??" If these companies really cared about waste/recycling/environment, etc they wouldn't provide any bags at all or they would issue pre-used bags.

But mostly I don't take my own bags as my husband likes making a point at the checkout (see 1st post)
