dealsstarbucks® espresso refill tumbler | freeā€¦


That seems exceedingly expensive for a tumbler, even if it does come with one free drink for every day you happen to make it into a Starbucks store... I guess if you have a grande espresso drink every day already, it makes fiscal sense, but if not, it seems like this would require a lot of extra coffee drinking to get the value out of it.
Some quick fun math:
Assuming the tumbler itself is worth $10, and the average grande espresso beverage is $3.50, you would need to use it a minimum of 16 days out of the 31 days in January to break even just over the $55 mark.
If you go every single day in January, you will effectively receive just over $105 worth of beverages for $55+10.
