Fine Print & Level-Up Pro Tips

App-only offer — the discount is redeemable only through the SONIC App's Offers mailbox. Counter and drive-thru orders won't ring up the $2 discount automatically.
All Refreshers are eligible — the promo covers the permanent Refreshers line plus this summer's seasonal standout, Watermelon Peach, available in sparkling or frozen formats.
Frozen Refreshers = the hot-weather move — the frozen Watermelon Peach doubles as a Refresher and a dessert. Great value at $2 off.
Order through the app for pickup so the deal applies cleanly — no need to ask a carhop or explain the offer at the speaker.
Sign in to Sonic Rewards to also earn points on the order — free drinks and food unlock faster than you'd think.
