So, is it really a bargain when you purchase something you don't need? And what about that tee-shirt from your older sister? Do you need that? Remember in purchasing things or accepting hand-me-downs that they need to also meet the criteria of non-clutter--either serving a purpose or bringing you great joy. And, if you have 30 tee-shirts already, a 31st isn't serving a purpose. Say no politely and let it go to someone that can really use it.
