Airbnb promotion code PAYPALSTAY25

[Rozbit]

Hello, I got an email with message: 

Not discovered Airbnb yet? We’re giving you £25 off your first Airbnb trip when you book with PayPal, so you can get your next holiday in the diary and make it feel that much closer. Just pay with PayPal and use code PAYPALSTAY25 at checkout*.

*The coupon is valid for a £25 discount for first time Airbnb users in the UK who pay for their first Eligible Booking with PayPal during the Offer Period, while supplies last. An "Eligible Booking" is a booking on Airbnb for £50 or more, exclusive of security deposits, cleaning fees, taxes and other fees. The "Offer Period" begins on March 9th 2017 at 08:00am and ends on May 31st, 2017 at 11:59pm. To receive the discount, you must (i) be a UK resident and have a valid Airbnb account, (ii) have never previously made a booking on Airbnb, (iii) request an Eligible Booking on Airbnb and have the reservation confirmed by the host during the Offer Period, (iv) enter the coupon code PAYPALSTAY25 on the check-out page before entering your payment details,

The problem is:

There is no place on airbnb site to enter the coupon. How to do it?

I am from Canada I had the same issue. We have $40 off for our first Airbnb stay. While booking through Airbnb I was on call with Airbnb rep to help me through the process and when I also ask her about the promo code field she told me that there is no field available to apply promo code. Then right after I called Paypal customer service after talking after 39:30 minutes and I ended up talking to supervisor and he simply told me that they is problem with your PC or browser and blah blah. I told him that I have good knowledge about computer and some basic software so don't fool me around. Anyways i ended up wasting my time. Sorry to say PayPal if you guys can't give proper service I suggest don't lure customer with garbage offer! Guys don't waste your time using this offer or any other offer in future.. I would rather pay with my rewards credit card so that I atleast get reward for my purchase.
