Announcement reposted from Amazon United States:
We’re making it easier and faster for you to create up to 100 coupons at once with our bulk upload feature, helping you scale your promotional activities.
You can now use a single bulk upload template to create Subscribe & Save, Reorder, and standard coupons in Seller Central.
While you still have the option to create coupons individually, the bulk upload feature makes it faster for you to create multiple coupons when you have large product catalogs or run frequent promotions.
To get started, go to Create coupons in bulk.
