Sonic Drive-In Master Blast price in 2026
The Master Blast is listed at $5.99 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.
