Crappy Gifts?

Yes... i should be thankful the thought was there. But for Christmas, birthdays, holidays... everything, both my mom and my aunt have bought me really really bad, impractical gifts. For example... a seatbelt cutter.... a bin full of carib clips that you can't use for climbing.... hospital lotion....a lamp that you strap to your head.... you get the point. The worst part is that I know they are actually paying a bit of money for some of the things they've gotten me. I live in a small apartment, and i hate to waste..so i get these impractical gifts, when throughout the year there are certain things i would LOVE to get, but don't do so. How do i tactfully say, if you have to spend money on me, please do it for things i will actually enjoy, instead of things i'm going to throw out bc they are useless and taking up space? idon't want to hear about how i sound like a spoiled brat, and shoudl be thankful. just give me a tactful way to approach this...ps.. they start shopping in february
