Re: minimalist family and out of control grandma buying?
When your mother gives you something, smile and say thank you. It's a gift and you will drive yourself crazy trying to find a way to make her stop. After you've said thank you, set it aside and take the bin to a consignment shop for them to sell for you.
You cannot change other people, and you shouldn't try. You've said your piece, and that's all you can do.
I run the Frontier Wholesale co-op in February, May, August & November
