Parents, do YOUR parents give your kids "stuff"?

We live far from our family, so my mom likes to bring my kids little presents, which is fine. But she brings things that are just clutter (my mom has collections, I hate collections), things they already have (ANOTHER box of colored pencils), or stuff she has collected like freebies which she has no use for and neither do we. For example, a bag full of shells that somebody else collected is not nearly as exciting as the ones you collected OR a figurine that was once meaningful to you, but pointless to somebody else. The "stuff" either gets piled up on their bookshelves/dressers, or tossed in the bottom of the closet. My kids already collect enough of their own "treasures", so the extras create nothing but clutter. I am nowhere near a neat-freak, but am trying to teach my kids to pick and choose what is important and not everything is meant to be kept forever. I know she wants to bring them something, but how do I gently tell her 1 useful, yet inexpensive gift each is better a bag each of miscellaneous items that we don't know to do with. And before anybody bad-mouths me, yes, I completely appreciate the thought, but all parents know just how quickly kids "stuff" can get out of hand, if you let it.
