I just picked up a copy of Daddy's Home 2 for $2.95 at Digital World HD:
When I redeemed the code in iTunes and downloaded it, iTunes indicated it was a double feature of Daddy's Home and Daddy's Home 2. I already owned Daddy's Home, so I really don't know if this is truly a pay for one and get 2 deal or not.
I thought I'd post in the event this is in fact a double deal. If not, $3 for Daddy's Home 2 is still a great deal.
Also FYI, the home page of Digital World HD states to use coupon code HOL15 at checkout if you spend more than $10 to get 15% off; it did not work for me. It said the coupon was for 12/29 only.
