The user will have access to the coupon right after they do what's required to see it.
For example, Twitter coupons require that the user tweets the coupon.
How can the coupons be redeemed in-store?
Each coupon has a unique code that can be scanned using a QR code scanner or
simply typed from the coupon print out. You can also upload your own Barcode and scan that instead.
You can see all of the coupon codes and the users who claimed them from TwtQpon admin page.
Is there a landing page? Where do I add the rules, expiration date, etc?
Yes, this page is the first step (out of three) to set up your landing page.
