What is the average best price per pieces of CITY themes?

[ks6349]

It's difficult to compare the small set (e.g. under 100 pieces) with some minifigures. For example, I got Lego 60184 with four minifigures and like 88 pieces for $7.99 while I got 60220 (maybe 90 piece only) for $14... 

For larger sets like with 200+ pieces. What is the average best price per pieces of CITY themes that you would think it's the best time to purchase?

Price is an important consideration for me because I like to buy Lego, but I am not urgent for playing, I can always wait for the good price.

City needs to lower the prices for their sets. They should make their buildings simple like they did with the 60215 Fire Station.
