why is everything sold out? well it be on sale again?

Everyone bought the stock the store had look for them on the market

I've always wondered the second part of your question. When will items be restocked? I once saw every first day of the month, but I don't believe that.

Yeah that's right, the torishop is restocked in the first day of every months. Untill then, you probably want to check the market to buy them ;)

ok thank you

Oh alright, thanks bro.

Orc trails are cheap and highly tradable thats why don't expect that it will have stocks.
Many marketers wait for the restock day and hour just to buy all the cheapest items with a large number of quantity.
