In case you enter a discount code during checkout that doesn't exist or isn't currently active, then you can see the message: “Unable to find a valid discount matching the code entered”.

Of course not, most coupons may be used only by you when you received them directly from Vayama. As the Vayama coupon includes your User ID, it cannot be resold or transferred in any way.
