Looking to find deals a used Dualshock 4

Been looking and saw some on eBay but missed my opportunity. Not looking to spend anything over $35 after shipping for a used Dualshock 4. Anyone care to point me to the right direction, please?

Or perhaps when there will be a sale on Dualshocks soon?

Check the Amazon Warehouse Deals thread. $35 for a used dualshock 4 won't be standard for a few more years.
