I'm selling sand in my spare time. Whoever gives me the highest offer per stack of sand, I shall sell the sand I get to them. Let the bidding commence. Not that this is an auction or anything.
You've been outbidded, Silken_thread's shop offers me 50r per stack. If you can beat that, I'll happily supply you.
I need a large amount of sand, i would say about 10 double chest worth to start with. I'll pay you 45r per stack.
