Sonic is running a special promotion on March 8, 2018 where you can get half-price shakes, floats and Ice Cream Slushes.
The deal will be available all-day at participating locations on Thursday, March 8. No coupon is required to take advantage of the offer, but I always recommend mentioning the promotion while ordering to ensure the discount is applied.
Sonic usually limits this promotion to five discounted items per order.
Sonic Nights Is Back For 2018
Additionally, Sonic has brought back its annual Sonic Nights promotion, where all Shakes, Floats and Ice Cream Slushes are half-price after 8 p.m. at participating locations. Floats are the newest option for 2018. The Sonic Nights promotion typically runs through the summer.
