I'd rather be cheap than green

I don't get it.
You gotta BUY these bags (plastic is free).
You gotta buy ENOUGH of them for all your groceries (because you can't mix green and plastic)
You gotta STORE them somewhere
You gotta remember to BRING them with you when you go shopping.

And then you gotta buy plastic bags for all your trash cans.

What if you shop at more than one grocery store? Maybe we have our values a little off (gas is apparently not as important to us...), but we get most of our groceries at Kroger, most of our bulk stuff and cleaning supplies at Walmart, and milk at Food Lion. (Kroger milk tastes funny to me and Walmart milk is the most expensive of the three. Plus, Food Lion sometimes runs a special where you get a "ticket" for every gallon of milk you buy, then you can redeem six tickets for a free gallon. But get this: you still get a ticket for that free one, so really you only have to buy FIVE gallons. And their milk is less expensive. And it tastes good.)

So are we supposed to buy a supply of reusable bags for EACH STORE?? And then. AND THEN! There's no discount or other incentive for using these bags!! I have to shell out money to use these special bags just because it makes me feed good about "saving the environment"??? Sorry. I just don't get it.
