OK...SR is closed now...I proceeded through checkout for 20 chassis, all silver face (Mike said no $5 up-charge for black faces):
Chassis $49
Shipping each to me $20
Subtotal $69 x 20 = $1380
One time SR $10 handling fee = $1390/20 = 69.50 ea
Add $10ea for cutting, $79.50
Add estimate $10ea shipping from me to you, $89.50, $179/pr (this is not your exact final cost...rather than $10 estimate as above you'll prepay me the amount printed on your shipping label which you'll confirm when it arrives)
AFAIK Mike @ SR requires single order, MOQ 20, for $10 per chassis cutting fee.
I estimate $200-$300 depending on geographic area for CAD/CNC cutting.
Above two chassis delivered uncut to my Utah zip code 84332:
Silver face $49 + 20 = 69ea, $138/pair + 10 SR handling = 148/pr...black face + 10/pr = $158/pair, but $10 fee varies depending on zip code.
So we pay about $30/pair more for fully cut chassis vs. $200-300 for local service (estimate).
I'm happy to spend less if possible, please post here.
