UPDATE
For those people who ordered switches that we have to source from 7bit rather than from our supplier (specifically MX Clear, MX (light) Grey, MX White, MX Lock), you should expect a supplemental invoice soon for the price difference between the GB switch price and 7bit's preorder price, plus a share of the shipping cost. Basically, we will be charging you the same price as if you ordered from 7bit individually, since that is what we will be paying for them.
The price difference for those switches is only $0.08/per switch, with shipping at $5.20 per order. Most people who ordered those switches should see a supplemental invoice for about $10 or so for the difference.
If you want to change your switch order to one of the switch types offered by our GB (specifically MX Red, MX Brown, MX Blue, MX Black, MX Green, or MX Dark Grey), just send me a PM, and you won't be billed any extra.
