Dealing with unwanted Christmas gifts

I would thank the given and stuff it away in a cupboard. Then when it became retro I would sell it in one of my online shops.

I used to hang on to unwanted gifts for years! Then charity shops benefited. I give money now and a small, often jokey gift, just something to unwrap. The main gift is the recipient's responsibility/

I have a friend for whom it is difficult to buy presents. The same item was returned to me the next Christmas. She seeks out the person who gave it to her originally and does not bother giving it to somebody else. I no longer give her presents.

Family know that we keep receipts for virtually every purchase and would far rather they asked for said receipt so they can exchange for duplication, sizing or not to taste.
No-one can get it right all the time so I'd rather they returned the gift and put the value to something they would rather have than re-gift or put in a cupboard never to see the light of day.
I have received some questionable gifts though - usually chocolates - even though I don't like them but DH and family have no problem in sampling them for me!!
