Continue getting packages from family I’m no contact with and it’s still upsetting

I got a package today that was addressed to my family (the __ family) so we opened it. Return address was a store somewhere in Florida. It was 3 pairs of pants size 10 (I’m size 2 so definitely not for me) and very much older woman style, and the billing address is my grandma’s name and address (my grandma who told my sister she’s ‘done with me’ over the holidays and cut me off after I had a baby and had severe PPD.. I posted about this the other day actually). In my whole life she’s never accidentally mailed me something, but neither has my mom who I’m NC with, and she also ‘accidentally’ sent me a package addressed to my kids a few weeks ago. For that, my mom texted my husband asking him to move the package from our porch to the mailbox so they could get it when they’re in town 😒 My grandma emailed me from her phone number somehow and said congrats on the baby (who was born 7 months ago) and something about the pajamas she sent for Christmas that I did send a thank you card for. She said please let me know you got this email and her new address to mail this stuff to. She’s blocked on my phone so maybe she tried texting first, I don’t know. What is the protocol here? Donate them, return to the store, or gift them to my husbands grandma? It seems like this is becoming a pattern.
