Select the exact drive-in first
Open the official SONIC app or website and choose the drive-in you will visit. SONIC says pricing varies by drive-in, so another location, an old receipt or a search snippet is not controlling.
Match the order format
Compare item-only with item-only, or the same combo with the same side and drink size. A delivery basket, app offer or customized drink is not comparable to a standard pickup item.
Audit every add-in
Drink flavors, fruit, candy, sauces, cheese, chili, bacon and size changes can affect the total. Review the final item name and line-item subtotal after customization.
Check promotion conditions
Confirm participation, account eligibility, ordering channel, required items, expiration and whether substitutions remove the discount.
Save correction evidence
Record the drive-in, date, item, configuration and checkout screen or receipt, while removing payment-card and account-security details.
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.
