6.0L ac compressor seized - cost?

[jage]

Ok so I'm out in Indiana with the van and right as I picked up the girls from the airport the ac started to smell like roasted brakes and stopped working. Took it to a dealer here (Tom wood) and got a pretty steep bill. I just want to double check before I take it in Monday for the actual service.

Seized compressor $1509.55 ($840+ for part)
accumulator (seized) $294.62
orifice (seized) $77.97
Flush (seized) $224.45

Breakdown parts $1300 labor 5 hours

Total (in pen $2300)

So online compressors are around $475, which I understand a markup, and they need to warranty. The thing that starred to nag me is they made me fill out and sign a paper with credit card info agreeing they would charge me for the part if I didn't come back. At the time all I wanted was it to be done asap. They also have an estimate for front brakes and rotors for $699 which I'm not doing and some other things.

So in the mix I also get a comp rental (no doubt a compact) for two days while they work and the place is five minutes away from our rental- so I don't mind paying a little premium, but my family has me all worked up like I'm paying double. Of course every dealer is closed by the time I write this but the question is should I shop around and fight them about the parts order or is it a small enough difference I can just get on with my vacation and not sweat it? Thoughts?
