How to order Diet Dr. Pepper at Sonic Drive-In
The Diet Dr. Pepper is available for dine-in and takeout at Sonic Drive-In locations across the United States, and through the chain's own app or delivery partners in most markets. Before you order, it is worth checking the current Sonic Drive-In deals in case this item is part of a running promotion.
Sonic Drive-In Diet Dr. Pepper price in 2026
The Diet Dr. Pepper is listed at $2.49 on the Sonic Drive-In menu we track. That figure is a guide rather than a guarantee: most fast food chains let individual franchises set their own prices, so the same dish can cost noticeably more in high-rent city centres than in smaller markets, and airport or stadium locations sit higher again. Menu boards and the official app are always the final word for your specific restaurant. We re-check the full Sonic Drive-In menu and refresh this page when prices move.
