Starbuck's most expensive coffee comes to $47.50

ENUMCLAW, WASH. -- One enterprising Starbucks customer thought it would be a novel idea to find out just how much a cup of joe could set you back. At an Enumclaw Starbucks, he ordered a frappuccino that included everything from 48 shots and protein powder to banana and strawberries -- all topped with caramel and chocolate. The cost? A mere $47.50.
