Should I give her the cash?

C

My cousin threw my baby shower over two years ago and it was amazing. We had 80 people over and she just did so much to make a shower I would be into. She also got a pool together to buy me a nice stroller, though jr was second hand, she paid like 500$ for it. Well now I’m going to sell t to a friend of mine who is having a baby and I honestly don’t want to charge her much because she’s my friend and I’m just so happy for her but I feel my cousin would be put off if I didn’t ask for some money.

So first question is would you be annoyed if u were my cousin in this situation and I didn’t ask for much? How much would u ask my friend for? Considering is a 4 year old stroller.

And after all that, do you think I should offer the money to my cousin?
