+1 I think Auntie is pulling a kind of scam on you. She knows it was a gift. She knows she bought it for $8. But she wants more $$ and praise. It was a gift and it’s gone now. No more gifts please.
OP here. This is what I think to, they both love scheming to get what they want. She isn't forgetful and she knows perfectly well that she only paid a few dollars not $100. If we were to refund her for the gift that we never wanted and tried not to accept at 1000% more its value, she would be super happy. More attention for the gift and $100 to go buy more junk. I'd rather throw $100 out the window.
