I'm sort of new around here but I think this is the wrong reddit sub homeslice. Correct one would be r/starbucks. The most helpful way to check the price of any drink download the starbucks app and plug in all the modifiers as it would adjust the price for your location. Drinks change depending on country, city, etc etc (at least thats my understanding!)

Your only customizations are light ice and extra mocha drizzle, which don't have any added cost (Disclaimer: extra mocha drizzle is an added cost if the drink does not already come with mocha drizzle. This frappuccino does get mocha drizzle, so extra is not an added charge)

Obviously sales tax applies based on your area, but it's probably like $5+
