I think Tyco owns a bit of everything. I'd put money on them having a peice of at least 50% of everthing you touch in the fire safety industry. $10 to $16 a roll seems about the average from east to west. If your paying retail for any of your supplies I'd take a good long look through the yellow pages to find a supplier for your cleaning products. The time invested in a little supplier research could save you hundreds, if not thousands per year.
