Ice addiction!

Tiffany • Had my first on April 9th 2015.
No I am not anemic or have an iron deficiency. Nor do I have pica! I just want to eat some ice here and there. So onto the subject....I want pellet ice and I was researching where to find it by the bag. I read Sonic drive thrus sell it by the 10# bag for $2.00. Anyone know??? I usually get the $1.75 for 20# bag of ice from the Twice the Ice place but just wondering!
