The Rokinon Lens Coupon party continues at Amazon with another 20% off clip-on coupon for the Rokinon 14mm f2.8 (Sony E) dropping from $300 to $240 after the clip-on coupon. Per the shopping cart, this is restricted to Prime members. The restriction is on the purchase of the lens, which obviously blocks the use of the coupon for non-Prime members. Coupon expires 7/11/17 PM.

Also eligible for this 20% off clip-on coupon is the Canon DSLR version dropping from $300 to $240. Same expiration date.
