So, I'm a newbie with this whole GST stuff and also a lot of other people don't know any or much information about the shop.
My questions are,
1. Do you need to be in a GST guild in order to get in the shop?
2. Does your guild need to win the first round to get in the shop or can you get in even when losing?
3. Can you get in into the shop even if you aren't a core or sub member like is it enough to be just in the guild?
4. Do you just get to be once in the shop or like, 1st round = 1 item, 2nd round (if won) 2nd item and so on or is it just 1 item per GST?

Thanks for the answers.  

You need to win your first match, and have 2,500 gralats to buy the random prize box. (They might have changed it)
All members of the team get to enter the shop.
1 item per gst, and you can enter every time you win a match.  

you don't even have to win the first round anymore, as far as I know from a few GSTs ago

I thought thats how it used to be and then they made it so you had to win the first one  

1. Yes. Your guild must qualify to enter the shop.
2. Win or Lose the first round you still can go into the shop.
3. Only the 7 that are in the GST are able to enter
4. You can only purchase 1 item per GST (1 winter, 1 fall, 1 spring, 1 Summer)  

don't forget its 2500 theres 7 items and you can only buy 1 per gst so 4 per year
