Finish are offering a mail-in-rebate for a free 20 count pack of Finish Quantum or $8.49 max value on any other Finish product on their Facebook page. There are coupons for Finish expiring at the end of September so it is a great time to buy them for the rebate.
If you don’t have Facebook, download the mail-in-rebate form here.
Thanks Arshes76 for letting us know about the rebate.
