Want an extra $5 on your Starbucks Card?

If you are unfamiliar with the Starbucks rewards card system, you might not know that you can transfer balances between Starbucks reward cards. Say if you got a stray $5 gift card from a promotion or as a holiday or workplace perk, you could take that balance and port it over to your regular Starbucks rewards card (or account, if you are using their mobile app for purchase transactions).

When it comes to content and design, the Starbucks email and accompanying rewards landing page are minimalist. The content certainly does do the job of providing a meaningful amount of information that has a targeted call-to-action which encourages a user to do other steps, maybe check into what else Starbucks is offering, check on reward status or account balance, etc.

What you might not know is that you can also transfer a balance from a cash gift card, say a $100 Visa gift card to your Starbucks rewards card at any Starbucks-owned kiosk or store. And, if you're a Coinstar customer, you can convert your deposited coin balance to a Starbucks rewards card without incurring any service fees.

And, if you're an avid coffee drinker, this is a darn good deal for 1 lb of whole bean coffee. 'Nuff said.
