I need to work on my pitch
I hate to disturb you again, good commoner, but my Cog Shop has recently expanded its selection with a variety of rare gems. Why waste your time scavenging for gems if you can buy them from me at the low low price of 5 coal and your choice of 5 iron or 5 wood? Check out your local Trading Post right away, because if you order today, I will not only give you this great product, but you will also receive it earlier than you would if you had ordered it later!
BUT WAIT! There’s more!
No wait, that was it.
To a certain other commoner who has also been working towards an Observatory and alchemarium: is there any way I can dissuade you from building one and competing with me? My profit margins are quite low already, and I doubt either of us would profit from a price war. I’m sure you can find another good use for all those resources, and I’d be happy to trade you your coal back, should you decide against this.

Given how cheaply you can produce these strangely gritty little gemstones of yours, your price seems a little expensive - the five coal and five iron you ask for a single gem is sufficient for you to immediately produce no less than five more such gems. Perhaps a healthy price war would be in our society’s best interests.
