Input: Purchased this case of 12 cans of Clorox Commercial Solutions Disinfecting Cleaner, but Office Depot only sent a single can. Since it's an aerosol, it can't be returned. Seems to be an outrageous price to pay for a single can of spray. Warning to any potential buyers: take your money elsewhere.

Listing describes a case of 12, Office Depot only shipped one can.
