Customer Appreciation Chip Credit Program

   As a thank you to our customers for being patient with us as we move towards fulfilling our shipping we are instituting a chip credit program for all pre-orders prior to April 1st, 2013 (Including orders already delivered). This program will allocate a $25 discount per chip up to the number of chips you currently have on order. For example, if you have a Single SC on order, you will receive a $25 credit per chip for 16 chips (Meaning 16 chips can be purchased for $50 each). The chip count for each unit is as follows:

   5 GH/s / Jalapeno: 2 chips
   25/30 GH/s Miner: 8 chips
   50/60 GH/s Miner: 16 chips
   500 GH/s Miner: 128 chips
   1.5 TH Minirig: 384 chips

   Every customer with a current pre-order dated prior to April 1st, 2013 will receive a chip credit for the number of chips/units they have pre-ordered. What this means is that you will be able to purchase raw chips from us for $50 instead of $75 per chip, up to the number of chips you have credit for. We realize that not all of our customers are interested in or have the desire to make use of the chips themselves. To that end, you will be able to sell your chip credit to other people who may be interested in or have the ability to make use of the chips directly.

   For our very earliest customers, the first three months of orders (June 23rd to September 23rd orders) will receive 2x the value of the chip credits. For example, a 60 GH/s miner will be worth 32 chips in credit, a Jalapeno will give a 4 chip credit.

   You should see your chip credit code(s) in your account shortly, and you may do with them as you wish at that time.

   There is a 100 chip minimum purchase, so if you are acquiring codes, please be sure to understand that you will need to order a minimum of 100 chips.

   Terms: While we do not have the facilities or the ability to facilitate chip transfers directly, the chip credit codes are transferable from one person to another and we do not limit the resale or transfer of the chip credit codes. The customer is responsible for doing their due diligence when buying, selling or trading the codes, so please be sure to only trade with trusted, verified individuals. Codes can not be refunded, returned or canceled once they have been used or transferred. Butterfly Labs will not be responsible for what a user does with their codes and we are only providing the discount to verified, paid pre-existing pre-orders. Once codes have been redeemed and the payment process has begun, if you do not complete the payment, the codes will be invalid and can not be refunded or returned.
