Just found this on Chewy.com

Greenies Teenie Size 5-15lbs 130 count $24.69. Buy two, get free shipping and if you sign up to their auto-ship (reschedule/pause/cancel at any time)  save an additional 15%.

I use these as an after teeth-brushing/grooming treat every night. With two dogs, I go through a 96 count  (.20/treat) package in less than a month and half. With this deal I paid .16/treat. It adds up folks.
