The "what should I add" question is never easy. It's not like 1 + _ = 5 where there is a clear and concise answer.
- The gold turnstile was never available in game.
- You had to have access to the parks (not sure even if WDW ever had it, anyone???) to get it.
- You had to complete the 50 Mickeys in game quest to get the certificate.
- You could only get 1/character.
- It has been retired for a while now.
- Although NOTHING is a sure thing these days in VMK, the gold collection was part of the 50th celebration for DLR so the chances of it popping up in game are small.
Now, what makes this fair: red + ___ = gold?
Sort of depends on:
How much you want it?
How many they have?
How much they want red?
And, lol, how aware are they of the above?
A gold snowman is for sure too much. A buyable item is too little. What makes it fair? That's where VMK gets to "What's the item worth to you?" And I would add to that, are you getting it to trade or to keep for yourself?
I don't know if this helps at all, but I hope it does somehow. Good luck!
