15lbs clumping pine litter (17lb bag)

Just purchased on Thursday Oct 8th Feline Fresh natural clumping pine litter. It's a chemical-free formula with low dust. Weight is approximately 14.9 lbs of a 17lb bag. Looking for $20 or Best offer. I am fostering a kitten and TAS won't take the bag of litter. I'm also on disability so these were unforeseen expenses!
