Pricing has changed.
It used to be that you'd be charged per drop and what not. Its more likely today that you get a set price to do all the work, not on a per line drop but as in "10 drops for $500 dollars" or something to that effect.
Ask for a block pricing, not a per drop pricing. Per drop is more expensive. They'll run as many together (say from Switch to Room 1 you have 10 runs) - They'll charge you $100 per run, $1,000 yet it was technically only 1 run since they were all done together.
