Here in Illinois if taking affect a law that you must buy a plastic bag or carry your stuff without bags. So I stared to use one bag and didn't see the benefit of using a recycling bag.
If you have a hard time remembering your bags....
Keep some in your car, purse, or backpack.
Hang them on the door so that you see them when you leave
Use boxes at the store then recycle afterwards
Carry your groceries out without a bag if you don't have reusable bags
Don't fret if you still forget them from time to time. Habits take time to form. That is why we have this 30 days challenge.
