Where do you get your re-usable shopping bags from? Here in the UK they charge you 5p for every single plastic bag you get from any chain retailer so for people here, buying bags that are re-usable is now a must. These 5p carrier bags aren't re-usable and you'll be lucky to even get them home before they break. Instead I try to make sure I buy bags that can be replaced for free if they break from the grocery store. I find this way at least I'm only having to shell out once for the cost of bags to carry my groceries home in. I don't like to use the same bags for clothing, pet food, cleaning supplies and human food though, so I make a point of getting different bags to use for different things. I usually use canvas type bags for cleaning supplies as they're a bit more robust if anything breaks or spills. I tend to use plastic ones for pet food and human food. Then I use cloth ones for clothes. I usually buy these at clothing stores. So far I've only had to replace one, but for £1 that's not too bad for how much use they can get.
