I purchased the rumble seat for the Uppa Baby 2014 for my cousins second child. It had to be for the 2014 or older bc they changed the stroller for 2015 and it wouldn't fit her 2014 model! I contacted Uppa and they told me to buy it here since BuyBuyBaby doesn't sell it anymore. I was impressed by their reputation with the vendor directly and the shipping was super fast! It came less than 24 hours later.
