-- \<p>You can create coupons easily via the \<a href=\"https:\/\/dashboard.stripe.com\/coupons\">coupon management\<\/a> page of the Stripe dashboard. Coupon creation is also accessible via the API if you need to create coupons on the fly.\<\/p>
--
-- \<p>A coupon has either a \<code>percent_off\<\/code> or an \<code>amount_off\<\/code> and \<code>currency\<\/code>. If you set an \<code>amount_off\<\/code>, that amount will be subtracted from any invoice’s subtotal. For example, an invoice with a subtotal of \<currency>100\<\/currency> will have a final total of \<currency>0\<\/currency> if a coupon with an \<code>amount_off\<\/code> of \<amount>200\<\/amount> is applied to it and an invoice with a subtotal of \<currency>300\<\/currency> will have a final total of \<currency>100\<\/currency> if a coupon with an \<code>amount_off\<\/code> of \<amount>200\<\/amount> is applied to it.\<\/p>
