Sold a component and bought it back, am I nuts?

I sold my brand new naim 5si integrated about a month ago, by sold, I mean I traded it in. I was looking on website of company I traded it into, and noticed in used section. I inquired about it and was told it was indeed the Amp I had traded. They had to open box up to check it out before resale, despite it being new. Anyhow, they had it listed at a greatly reduced rice. Me, knowing it was my former amp, I scooped it back up...am I a genius? Lol...
