You might get the IMEI off a document but the WIFI MAC address is also needed and that comes only on the phone.
Where are you guys getting this wifi mac needed from? I used the Shop Samsung app. Logged in with my Samsung account and submitted for the promo by attaching lease agreement confirmation. Took less than a minute to respond with approval and I was given a choice of the free only or the $99 bundle. I didn't have to wait for any email or anything...I choose the bundle and paid right then and there.
