Potion Kegs

[Varak]

is there a decent demand for empty potion kegs and if so, at what price? 

When i look at all the seperater builds and varied materials, I can't see selling them for under 500. if they go for 750, it would definitely be worth it. if there is someone selling for 400, then i won't waste my time.

Any help is appreciated.

Thanks,

Varak.
