Now that I have a few minutes. Here's why you should be better. If you look at the other items offered, you'll find this.

Those are minimum 4" in diameter, they use minimum 16" of 4" diameter aluminum bar stock to make all 4. Even in volume, there is almost 100 bucks just in material. If they are cut from tube, even more. There is more than 10 minutes of machine time per spacer. Then they ship free. Plus packaging, plus handling, plus shelf space, plus a lot of things that it takes to run a business.
There is no possible way you can do that price with US goods, at all. And to be very clear, the only tiny little aspect that I have any issue with is just the disingenuous nature of saying they are made in USA.
The same is also true for the seat riser kit. You can not do those prices with US goods. Buchanan doesn't have a patent. Buchanan did however, do the first seat risers for the TJ and then everyone else copied them. There are two schools of thought there, those that like thieves tend to adopt the position that competition is good for the consumer, the other is the opposite.
FYI, 50 is not the same as 44 since that roughly 6 bucks is more than the entire profit in the kit.
Bolts in volume- 80 cents each = 6.40
Anodizing in volume = 8.00
Hole drilling and deburr 2 sides = 8.00
Cut to length on CNC saw = 4.00
Material cost = 10.00
Total if done in the US = 36.40
That is less packaging, overhead, shipping, etc. and then here is the killer. I have a lot of friends who sell on eBay. The barest minimum you can sell for is 12% in fees. That's 5.32 just in fees.
Those being a US product is not a sustainable business model.
