Anyone know of any particularly cheap deals from a residence to/from DTW?

It'd be nice if they discounted for round trip, early booking, etc.

Any good rate comparers online, perhaps?

What is the starting/ending point? I know of a service from Toronto (yes, Toronto) and Ann Arbor, but that's about it

They have uber over there yet? Very popular right now in GR.

I will second uber but they're generally not allowed to pick up at airports, at least that's how it is in Chicago.

Uber wasn't really an option -- I needed to reserve well in advance. Given how screwed up my return flight was (5-6 hour delay, TSA fucking me at every hop), that was for the best.
