To be put out a gift was sold on?

Long story short, gave some baby things to SIL a little while ago and I've just noticed all of the items have gone up for sale on Facebook marketplace.
AIBU to be a bit annoyed that she's selling them rather than offering them back or giving to charity?

I’m currently desperately annoyed because SIL returned a lot of our kids’ baby stuff to us that we’d given for her youngest. She said she wanted to make sure we could get the cash for selling it.

And now the bastarding stuff is back in my house when I thought I was rid of it.

I've lost count of the amount of baby stuff that I really needed and then when I got it, I either hated it or wasn't suitable (my superchunk firstborn was too fat for the Bumbo seat, for example). It could be that she doesn't like using it as much as she thought, or it just isn't suitable for her baby.
It was a bit crass to put it on sale where OP would see it though.
