TODAY is the last day that Costa fans can grab a hot drink for just 50p.
The coffee chain has been selling all hot drinks at the discounted price for registered Costa Coffee Club mobile app users since Tuesday to mark its 50th birthday.
Customers have been able to get the deal from April 13 to April 15 as long as they scan the app when they purchase.
The deal includes speciality drinks such as a handcrafted oat milk Flat-White, the signature Hot Chocolate or even the newest addition to the menu, the limited-edition Toffee Spiced Latte.
But there are some limitations as you're only allowed to have up to three extras or an alternative milk.
This promotion is open to new and existing registered Costa Coffee mobile app users so don't worry if you haven't downloaded the app yet.
However, customers were left furious on Tuesday when the app crashed due to popular demand with the 50p deal.
Many took to social media to complain about not being able to log in, with one user writing: "Really disappointed as I was looking forward to my 50p Costa."
When The Sun tried, we got an error message saying: "Oops! Sorry, it's not you, it's us. Please try again later."
The app, which you can get the app completely free from Google Play or the App Store, appears to have had no further problems since Tuesday.
To sign up to the app, you'll have to include some personal details, including your name and email address.
If you're too busy to stop by your nearest coffee shop, you can also get the offer through a Costa Coffee Drive-Thru or using Click & Collect via the Costa Coffee mobile app.
All Costa Coffee stores are currently open for takeaway, Drive-Thru, Click & Collect and delivery.
Costa also re-opened its outdoor seating areas in England on Monday as government guidelines changed.
Each store has been equipped with protective equipment, hand sanitiser stations with floor signs, and high-quality Perspex screens at counters.
The chain has also introduced designated pick-up points for mobile order collections.
Customers visiting Costa Coffee Drive-Thru sites will see a bespoke one-of-a-kind serving hatch has been installed to ensure customers can collect their order with no contact.
These cleverly designed hatches, which lower items down to customer’s vehicles, have a built-in acrylic hygiene screen to provide maximum protection.
