I know it may cost you some more money but next time you have personal stuff that you don't want her going through put it all together in a box, take it to the post office, then mail it to yourself. Not only is it illegal for her to open/throw away your mail, it's a federal offense.! Just trying to think outside of the box:) and good luck!

It's not YDI it's SDI (she deserved it)

Yeah sometimes moms are just ho ho hoes.

if I were in this situation I would of given everyone whose present been thrown out a letter saying what they got for Christmas and how much it cost and include a price of how much value they would of valued it and then tell them why they are just getting a letter

Well, they deserved it. Haha.

There have been an awful lot of parents just throwing stuff away recently... Or giving it away. What's up with that? My mom always made me pick out the stuff to get rid of from my own room. She would just ask if I wanted to donate/sell anything.

She knew what she was doing. She wanted to spare you the humiliation of giving horrible gifts to your family, and spare them the hassle of returning the crap you foist upon them. Listen, boxes of dead birds, rusty plumbing fixtures and rancid waste fry grease do not make good Christmas gifts. Just because you love those things doesn't mean anyone else does.

Step-moms are the worst. Sorry OP. FYL.

She'd better not complain when she doesn't get a present from you.
