There is a pawn shop about an hour from me that has been advertising a peacock emperor (for an okay price) for several months now. I don’t know how to copy and paste on this thing, but I’ll p.m. you how to find the ad. They’ve been trying to sell it for long enough they may be willing to dicker and ship! If you get it or any Windstone shipped though, be sure the seller double boxes and uses bubble wrap not newspaper, and insure the package.
As Etruscan said, the color is officially retired, but if you’re going to collect a retired color you picked the best. It was produced longer than any other scheme I think, and frequently turns up in the resale market.
