Some questions abour the store (coin)

Hi,

I wonder what is the rule for what items will appear in the store (coin)? I only play WotLK in Icecrown and there are items that I really want which cannot be purchased from the store.

I have saw people in game with Ethereal Soul-Trader (https://www.wowhead.com/npc=27914/et...er#summoned-by), which they received as new year gift; I have also tried to farm Time-Lost Figurine (https://www.wowhead.com/item=32782/time-lost-figurine) for a very long time but it just won't drop. :(

BTW, I also wonder how to add a link in forum which has a preview. For example, in the post https://forum.warmane.com/showthread.php?t=480330 the author had `The 2 Ring` which even has a preview when mouse is hovering.

Best wishes.
