Nice service! Please clarify some logistics though:
Are people supposed to buy the kits through massdrop, receive them, then mail them to you? Or you can also buy on their behalf from massdrop if you get paid in advance?
Also regarding the stem/spring swaps, are users supposed to find all parts and send them to you, or you have the required alternative stems/springs, and what cost, if any, is involved for these parts?
Finally, do you have red and brown switches (since massdrop doesn't currently) and what's the extra cost to add them ?
