🤔 National Vanilla Milkshake Day: Frequently Asked Questions
Do you need to buy food to get the free milkshake?
It depends on the restaurant! For the biggest giveaway at Wayback Burgers, the 12oz vanilla milkshake is 100% free with absolutely no purchase necessary. For other spots like Potbelly or The MilkShake Factory, the deals are structured as buy-one-get-one-free promos, meaning you will need to buy a regular item to trigger the free reward.
Are these milkshake deals available through third-party delivery apps?
Most National Vanilla Milkshake Day promotions are strictly limited to in-store orders, drive-thru visits, or orders placed directly through the restaurant’s official mobile app for pickup. Third-party delivery services like DoorDash, Uber Eats, and Grubhub generally do not support these location-specific holiday freebies.
How do I make sure my local restaurant is participating?
Because many national fast-food and burger chains are run by independent franchisees, participation can vary by location. The easiest way to verify a deal is to open the restaurant’s official app on the morning of June 20th to see if the coupon is active at your nearest store, or give them a quick call before heading out!
