I once had an 8 way train deal going on back when I was active in scale model trains and Lionel trains. There are times that money isn't good enough, especially if they don't need it. Then you find out what they want, and get that and do the trade.
But to get what they need, can lead to another deal to get that item. And on and on and on. I was so deep in it, I forged ahead. A bit of time and a lot of haggling, but I got all the deals done and got everybody what they wanted, including me.
Now about 40 years later, I remember the deal and what I all went through to make it happen. I don't remember what I had to have that was worth all the work though.
