I have some relatives by marriage, the same thing. At Christmas I'd mail their gifts and I'd never hear anything as to whether they received them, liked them, threw them in the trash, already had 10 of them, nothing! Soo, I just quit sending anything. I believe the main problem with my relatives were that if it didn't cost a lot of money, like in the hundreds, it didn't mean anything to them. A $50.00 or $60.00 video game or collectors doll was "nothing" to them, they wanted big things like $500.00 and $600.00 game consoles which I just couldn't do.
