Oh girl, what a mess!! I personally, would just not buy her anything and let the chips fall where they may. But, that's just me! I think that it only adds to their attitude of entitlement. BUT,..if for the peace of the whole holiday and not causing a total family explosion, buy her something she can't sell, pawn or bother you if she gives to someone else.Maybe a $20 GC to a local restaurant, or something in a small gift bag along the lines of a pamper-me basket:lotion, nail polish, nice buffer/file. Just something for a pick-me-up that won't cost a lot, but can be used more than once and no one else would care to buy from her for $$$. Anything like that would be a nice thought and you won't have to stress over it. Or just a nice candle. I love getting a candle from my friends~ I am sensitive to scents and only have a few that I can use, so when I get my favorite I am a happy girl!
