I thought it would make little difference, but in fairness I think it has
The bags Sainsburys for example are selling are comparatively tough ones, and the ones they used to give away, which were very useful for other purposes, are now no longer available. We have no other use for the stronger bags, except as re-usable shopping bags.
Mind you, it does seem strange that people would rather not fork out in places like Matalan, having already spent a lot on whatever junk they sell there.
Just shows our mentality when it comes to parting with money :-)
