Actually his take would be 10 BTC -- 10% of the total as noted in the OP.

!!! Group Buy extension until 30 April for SP10 deal !!!

After negotiating with Spondoolies Tech i managed to get:
- The Group Buy will be prolonged until 30 April 23:55 CEST time;
- When Group Buy will reach 700 units sold ALL participants in the Group Buy will be able to buy SP10 units for $3,400 or $3,000 if they had a previous purchase from other companies under the following terms:
           - Shipping: will be done after 18th May, but some may receive their units faster;
           - Payment: as soon as they showed their interest, 4 days grace maximum. If payment not received in 4 days they lose the shipping queue;
           - Stock: first come first served! The offer is for a limited stock of units and is only valid as long as they have the stock to offer them. They will only charge what they can ship.

No additional reservation fee required.
