This may have been asked somewhere else, but how can I order 3 S3's and use my three remaining coupons on the one order? Or can I only use one coupon per order of 2 miners?
One coupon per miner... just like at the supermarket.

That's what I thought. I ordered 3 on the site, and at checkout changed the 1 to 3 on the coupons, but it only applied one. How can I fix this, and order 3 with the three coupons?
