I use mainly cloth tote bags or Hessian shoppers for my " ordinary " shopping.
My supermarket items ( big shop, once a week ), goes in 2 of those insulated picnic baskets with handles. Cost about £6 from B & M/Home Bargains. These sit nicely in the supermarket trolley. I use the scanning handset as I go round and pack directly into them. A few people have stopped me to say what a good idea. Easy to lift in and out of the car boot and into the house.
The only plastic bags that come into the house now are MrLP's Iceland delivery ( once a month ), and the thin blue ones from the plant stall at the local market. I try to remember to take these back with me to re-use.
Any random bags that come into the house (ie with gifts or posted items ) are re-used as collecting bags for the charity shop. I always have one on the go and when it's full, off it goes!
Having said all that, I've just realised that I do buy plastic bin liners, as I don't like messy things like food waste going straight in my bin. Our area is supposed to be getting a food waste recycling bin sometime this year. The bag in my inside recycling bin gets re-used until it tears.
Gone are the days when I used to have a huge collection of plastic bags that might just come in handy!
Take care all xx
