Hey there, I am fairly new and I am learning both economies of the game. I am starting to learn about how much a pink should sell for at low levels and also how valuable platinum is. With the announcement of the game going cross platform I wanted to know this about the market:

1) Is it tied to a specific character, a specific account, or a specific i-Tunes account? I want to know because when I get the game on my Android device I would like to continue using this account I made which is not set up on i-tunes, and I would like platinum to not go to waste.

2) About "pinks"... I see people selling pink gear and some people are advertising them at just 1,000, but don't say what. Is it 1,000 gold for low level pinks or are they asking for 1,000 platinum?

3) Do some of the platinum purchases combine? I see you can add extra slots to your stash. One says 5 slots, another one is 75 for example. If I purchase both of them do I get 80 extra slots?

Thank you in advance for the answers, I really appreciate it.
