Are you going to to the install or have a shop do it? If having a shop do it, have them price things out for wheel build and them sourcing parts + install vs. you providing parts + their install labor. Buying online will certainly be cheaper if you are doing the work yourself; if you are having a shop do the work, it might come out very close or close enough to go with the shop pricing.
Into what kind of bike are you installing these wheels? Vertical dropout -- "Safety eyes 8L / 8R (green / blue)" -- yes?
Will you be buying lights, too?
Once you get everything tallied up, you may find the shop as cheap or certainly competitive, vs buying online and having a shop do the install. Figure shipping into the cost of anything you are ordering, your familiarity with bike mechanics, and the decision should be more clear.
