Alright, updated my first post to start a list. Once you guys have signed up with Brian (snowborder714) over at Tuners, let me know and I'll add you to the list. Realistically with 4 or more confirmed purchases it'll be worthwhile combining them as that's when you'll be seeing some shipping savings. I can do brokerage myself at the Kelowna CBSA office which will mean no brokerage fees at all, and as all the parts are manufactured in the states there shouldn't be any duty either, just tax. Once they arrive I can send them out by your courier of choice.
Of course, all this is dependant on the final shipping costs, but once the parts are ready I'll get in touch with Brian and see what the difference will be shipping everything to one location in Canada then piecing it out here versus just shipping it all independently. However for brokerage UPS charges $51.20 for the value of the machined parts ($400), and $80.85 for the value of the coilovers ($1700), as well as a 2.7% surcharge for paying the taxes up front to CBSA. I won't be charging a penny for brokering (gotta do it for myself anyway), and no stupid 2.7% surcharge, so I'd imagine it'll still be worthwhile combining everything.
Another option, if the shipping costs themselves don't merit this group buy, is that I can broker your package for you (as it can be done from any CBSA office), that way you still save the $55+ in UPS fees.
