Rumford Pet Center / Something Fishy, Inc. in East Providence, R.I. sells Flourite for $19.99 per 15# bag. I bought 2 bags for my setup last week. I need to find one more bag of Dark to finish my scape. I'll be going there today.
$19.99 for Flourite in Petsmart in Virginia as well. Even if online pricing is cheaper, any savings will be absorbed by high shipping charges. $20.00 minus shipping charges isn't bad.
Now if the store - price matches online stores, that would be really cool.
