Sales bldg questions

[Guest]

I'm sure this has been asked before but I've been messing with the gas stations market a little bit, in Germany. I bought some gas at Q27 off market for 90 and some Q0 at 70 per unit. To sell the Q0 in a day I would have to sell at 45 per unit. I haven't tried with Q27 but it would take about a week at 110. Why is the price on market trading far higher than what its worth? Is there something I'm missing? I've seen people offering to buy gas for 70+q on contracts even.

And how do I read what the numbers on quality means? There's two different ones in the stats.

Also how do the different levels affect sales buildings?

Well you need to sell gas at such price that you maximize your profit and not necessarily a full rack in one day. You should try selling at different prices to see the time required to sell, and from that calculate the optimal price.

I am not sure i understand the two different qualities in the stats, could you elaborate a bit on that?

Level does not affect your sales buildings, only the production buildings.
