I accidentally sent somebody more than what they purchased
So, I sold a bundle of my little ponies, and I had 2 separate listings. This person bought one bundle, but I just so happened to put ALL of the ponies in one bag. I was in a rush to get them out and I accidentally sent this person ALL the ponies even though they only bought ONE of the bundles. Then somebody bought the other bundle, and I just realized that I sent them ALL to that one person. I'm sorry if this doesn't make sense. It's confusing me too lmao. I genuinely don't know what to do. I don't want to ask the person to send them back, because it was my fault. Does anyone have advice? I've never done anything like this before, usually I'm careful😭I'm just upset because I was selling both bundles for $25 each so I could've gotten $50.
