In regards to Wizard Tokens:

I know there will be some variability because there's a lot of luck in vending. But on average, is it more profitable to vend and sell the goods, or to just sell the raw Wizard Tokens?

It always depends on the machine you vend at. Personally I only vend to try and get any new items released. I find it's more profitable to just sell the tokens because most of the items you vend are very deflated in value anyway.

depends. After vending thousands of times and autopricing everything you get then vending. Instant, much easier profit, just selling the tokens.
