Pretty far out. If you mean the actual company "4wheelparts", darn right they will take your money. They are good folks, but they know how to make a buck.
If you get the spacers as cheap as you can, you can install the rear yourself, I'm sure. Order new struts for the front and have them put the spacers in for free when they install the struts. I haven't found a shop yet that won't do it.
If you decide to do the front yourself, I have instructions. I think you'll find the above to be the fastest, least labor intensive, & cost effective
They usually charge about $50 a strut install and another $50 for the line-ment.
Say it was $305 for the complete kit as listed on ALLJ. $250 for new struts, install, & alignment, you could even throw on new rear shocks and be below $650
If you order this part# KJ09117, The price would be even lower.
Here are the instructions for the rear:

(item#6 can be overcome very easy without a spring compressor)

You might consider a coil spring lift too.
Hope it helps.
