Do you wash out the kitchen cabinets every day? The fridge?
What the heck did we all do before these plastic bags came on the scene to infest us? My mum took a bag to the grocery store every day. Nobody in my family died of food poisoning, or ever got sick from it as I recall. Oh, and we didn't have a fridge, and I can't imagine how we survived that . . .
I bought a couple of those "repeater" bags months ago (may be even two years now?) at my local rural supermarket for 99 cents each. The grocer gives me 5 cents back every time I use one. I'm well ahead . . . best investment I ever made. And I haven't washed one yet!
Of course, I don't always remember to toss the bags in the car . . . but I bet we've saved a few hundred bags. I still have them put stuff in a paper bag once in a while, then use the paper bag to take the newspapers to the recycle bin at the transfer station.
