i shop at sainburys and keep bags from them for the purpose of re-using them, only trouble is, you cant re-use them because they split so easily now due to what they are made out of. I re-cycle as much as i can and have got the kids into the habit as well, so when it comes to places charging me for bags it does annoy me if im honest. The worst one for this is the BP garage thats also a marks and spencer. All their products are so grossly overpriced and they still have the cheek to charge 5p a bag, again which is made from recyclable material.
