I just spent the past hour going from guild store to guild store trying to buy the pieces I need for the swamp jelly rune box. I've been using Tamriel Trade Center to go to guild stores where the pieces I need had been seen recently, but consistently I was unable to find any pieces. So I decided to just buy the completed runebox, and sell the pieces I do have to offset the cost. Except I can't sell the pieces I do have. I have no idea if this is a bug or normal, but can someone explain to me why rune box fragments are invisible in guild stores, and why I can't sell my own pieces?
