Front tires wearing on outer edge

Toe in was 3/4" too much. All fixed but shop pointed out that my upper and lower a-arm bushings are dry rotted and while I was at it should replace torsion bar bushings. They gave me a quote of $730 parts and labor. Does that sound reasonable? They said it was 3 quarters of a day job and I could wait til fall if I didn't have the cash.
Correction, not torsion bar bushings the quote is for strut rod bushings.

I thought $730 seemed high!
