Rufio, the Receptacle Representative, will buy your vials!
Bring him plain old vials, full or empty, and SELL them TO
him. He'll pay you a bit of gold, and you'll be doing your
part to keep Achaea beautiful and, hopefully, faster!

The details are in HELP RUFIO (or HELP SELLING VIALS).

He usually hangs out around New Thera.

Penned by my hand on the 7th of Ero, in the year 456 AF.
