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 I a genius? Lol...


@elliottbnewcombjr I did not do anything with it, as I did not receive any money. I am recieving my amp back that was traded in a month ago. However, should I decide to sell it on my own, then yes, I'll see $$$$

I'd say it was a great move, a $1999 AMP FOR $999.  It was brand new Still sealed in box upon trade in. The merchant had to open box to inspect, regardless of it being new. He took photos and placed add in used section. There were no bites, just low ball offers. I saw my Amp in used section and come to find out it was the same one I traded in. So, knowing it's history, I bought it back at the above $999. I was given $1800 for it towards the trade. Show me a better deal!. If I keep it, a win, if I sell it, even bigger win. I will most likely keep it. 

if they gave you way more in trade-in than what they posted it for, there is only one explanation that makes business sense: they acquired the item that you traded it for, for a lot less, and $1800 was just nominal. No retailer will offer x and then post it for x/2
