Do you LIVE for coffee shops? If you don’t frequent a large franchise coffee shop, it is worth it to check with your local coffee and tea shops to see if they offer the same discounts.
Many Gas stations offer a similar deal. My local FS has a great deal: buy your mug (3 sizes to choose from) and your discount will vary depending on the size mug you buy...Regular is .10 cents, Mid size is .15 cents, large is .20 cents and the extra large mug offers a .25 cent discount! A regular cup of coffee only costs .80 cents, with mug that is down to .70 cents! (They use Ronnoco, I LOVE their cappuccino!)
