I see no place on their order forms, or a way for that matter, to use S2 coupons to apply to the S4 to get another $200 off besides the coupon they just issued for $200. Can anyone confirm that they are allowing S2 coupons to be used for a discount?
I believe you can only use a single coupon per order--they don't stack.
@BITMAIN, please clarify, is it one coupon each order or one coupon each unit?
Earlier for some products like S3 multiple coupons can be added to a single order.
But for these discount coupons its not possible.
You can only use one coupon per order. If you are buying multiple miners then order them separately with multiple coupons.
