There's little online about these house-brand sodas at Walgreens, sold in the refrigerator case. They were apparently introduced in the fall.
They're sold in 16-ounce glass bottles and the price is about the same as other chilled single beverages, around $1.39, and they're on sale
3 for $3 this week with coupon. They come in cream soda, root beer, orange and black cherry, and they're made with sugar -- and no high-fructose corn sweetener.
I tried the black cherry and found it as good as any I've had.
