Re: long life bags
"In my experience long life bags just fill up the cupboard under the stairs or a kitchen drawer. Seriously we've got a least a dozen, plus hessian shopping bags, Sports Direct bags etc."
So why don;t you just keep them in the car where they will be handily available for the next big "shop" instead of building a collection in the cupboard?
On a related note, I see that quite a lot of the "bag for life" ones in supermarkets are just a heavy(ish) gauge plastic bag and some really don't look like they have much of an extended life expectancy (yeah, yeah, the shop will replace it if you can be bothered to ask). But just how long are they lasting in normal usage compared with the number of single use bags that could have been made from that same amount of plastic?
Here at Brown Mansions, we have an ancient Aldi bag that is huge, so big that it's easily possible to fill it to such a weight a single person can barely carry it, a large Iceland insulated bag, an fairly large maroon coloured one old enough that I don't remember which shop we got it at and a couple of carrier bag sized hessian ones. Most are older than the carrier bag tax because to us, a couple of decent sized bags make a lot more sense and are more manageable than half a dozen cheap plastic carriers.
