ScoopFree Litter Disposable Trays

If I’m reading this correctly, one order = one tray. Is this correct? The Specs list it at 2.2 lbs. but In the Box says 4.5 lbs which would imply that there are two trays in the package. I pay slightly less than $14.99/tray with my Amazon subscription so this would be a great deal only if there are two trays per order.
