Where to buy a lift for Hawaii DIY-ers? Home? Or the continent?

Hey guys, Iʻm looking to do a lift on my truck (2012 v6 4dr short bed TRD OR) and searching for places to get a good deal. I live on the big island, but will be traveling to the mainland a couple of times in the next couple of months.
Iʻm looking to buy a bilstein 6112 front setup with LR UCAs, bilstein 5100 in back with an AAL, diff drop, tp14, and maybe a sway bar relocation bracket if needed.
If I can get 3 free checked bags on Hawaiian airlines (because of corporate ticket through work) would I get a better deal to buy in Vegas or CA than buying these items at home in HI? With the cost of freight, shipping can be a bitch! I been looking at Top Notch in Hilo, or the performance off road shop in Kona by Costco. Iʻll be doing the install, just looking at saving a bit on cost. Thoughts? Thanks guys!
