Remember alignment is included in that cost, that could be up to $80 of it. I'm not sure how much the labor is on tie rods. But are you getting inner and outer done? You'd probably be able to find a shop that could do outer for cheaper then find an alignment shop that will align it for $50 or maybe less if just front end.
It's really not hard to do yourself, just need some muscle. I did it at night in the rain.
