Choose the base first
Start with the correct soft drink, tea, limeade, water, coffee or other base. A similar color or flavor name can represent a different recipe.
Lock the serving size
Compare the same size because ice, beverage volume, price and nutrition references are serving-specific.
Add flavors one at a time
Flavor syrups, real fruit, candy and cream components can change both price and nutrition. Review the updated item summary after each addition.
Separate zero-sugar claims
A diet base does not make every added flavor, fruit or topping sugar-free. Check the complete build rather than one component.
Plan for travel
For pickup or delivery, consider ice melt, foam, whipped topping and travel time when choosing size and preparation.
Use this guide with the menu database
Open the full menu, filter to the relevant category and compare two or three detailed item pages. Then rebuild the intended order at the exact store and channel you will use. This sequence gives a more reliable answer than copying a national-looking price from a snippet.
