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 Fandemanga. As the Fandemanga coupon includes your User ID, it cannot be resold or transferred in any way.

To avoid this problem, you should check out carefully Fandemanga promo code before that promo code could be expired, some promo codes are tied to a minimum purchase, a first-time purchase, or tied to geography, and other reasons.

It depends! Normally, the percentage that you can save with that Fandemanga Coupon will be shown right on the page, so you can see if it is applied sitewide or not. However, once you are not sure, try it right on their's products you want to buy.

The sitewide discount from Fandemanga is applied on certain purchases. For Year-End Deals, the store may have its own requirement to offer you a sitewide discount.
