Hi!
My son is more of a collector than a trader, he pretty much keeps everything unless its a duplicate from a mystery box. There are several locations both in the parks and Disney village, so if you're interested in trading, check them all if you can before you do.
Back in the states, they use these black boxes for you to choose a mystery Vinyl from the ones they have, but at DLP they just let you pick whichever it is you want.
DS traded new in box Phineas and Ferb Vinyls back in February, and the CM was so excited to see them as they don't sell them over here (they were ChristmS gifts from the states, but already had them) ...and the guy standing next to us snatched them up immediately. Lol so be sure to check all the shops, there are good ones to be had!
And while its a bit sneaky, I also buy clearance/cheap Vinyls for DS to trade. I paid for them, they're new...albeit cheap...and he wants to trade them. So I guess it's ok.

I ordered some $3 ones online and will be trading them next month...They're US ones, so maybe I'm doing someone a favor. Lol ...so you can trade any kind you have (the regular ones, not the really big ones) for whatever they might have. Usually each store has 3-4 on the counter by the register.
Good luck, hope you find some good ones! Last trip, DS bought his first Star Wars Vinyl, and got Darth Vader...not sure if he was happier about that or being in Disney.
