this is only possible if you used coupon for an expensive early order.
That's why I try to get at least one miner from every batch.
Thanks, but not very clear. So, I cannot use two of my own coupons on one order, but if I have a coupon and bought another coupon from someone, then I can use two?
This is not very logical.
Yes that sounds weird and I think it's mostly miscommunication. You should be able to use two of your own coupons on one order.
