Okay, I'm a little confused here.
When I go to the Buyer's Center currently - I'm still working for Mira Luna, BTW - I can buy more stock for any item I still have in stock, but can't buy anything else. Even items that we had in stock but are now out of stock, I can't get more of them. On the bottom of the screen, it says something like "Available styles to buy: 0".
From what I remember of the first Style Savvy, it was a question of available room in your shop, but I could always re-stock items I had already carried. What am I missing?
Also, when going to the buyer's center, I wish there was a more convenient way to see what you current have in your shop/had but are out of stock on. Like a stock list across all brands or something. Going shop-by-shop, and then item-by-item, is a little annoying.
