Oh my, that's shockingly cheap from my perspective.

In the downtown core of much of the east cost US, you're looking at $20+ for a minimum period of 3 hours. On the other hand, in my small city in the midwest during my adult life parking has gone from $.50/hour to $1.60/hour, and people have been outraged by each incremental increase.

Edit: noted that $20+ is often for multiple hours, but you regularly can't buy a single hour for $7, you're stuck paying a min of $20 upfront.
