I love the Pepsi Freezeway slushie...you have a gazillion flavors of slushie...can't you have some diet ones? A diet Pepsi one would be perfect, but you could also do fun things like pina colada..
Lots of gas stations used to have Parrott ice slushies, now no one has them. They were the best slushies EVER! Would love it if Sheetz would add that to their beverage choices.
