I have Ordered 16x L3+($462) with 1x 420 and 15x 350 coupons on 10 April.
But few hours later, support told me that the order will be canceled due to coupons issues.(the coupons can only deduct no more than 50% of the product price).
Then i re-order 12x L3+($462) again with 12x 200 coupons.
$462-$200=262 still sweet.
Not too bright there champ. You just fell for their "clearance sale". When the 16nm L4 comes out in July you'll still be upside down on those things. When will people learn?

? What do you think the Scrypt hash rates are gonna do when a miner hits that's twice as efficient?
