Ok, you got to tell me, how do you get this link? It isn't uncommon for me to want to get this for my kids (each of them). Just use two different browsers (Safari and Chrome) and I have no problem. But how do I get the link in the first place?
EDIT :
Figured it out, use the StarBucks app on the iPhone, go to Home -> Messages and see where it has the offer. Press and HOLD the "Download Now" button. It will prompt you Open, Add to Reading List, or Copy. Select Copy. Now just paste it wherever you want, such as here. Everyone gets it!
