As noted, Disney Plus are increasing their prices from 23rd February to £79.99 per year or £7.99 per month. A 33% increase on current pricing.
I realise their is a thread about getting in early, but found a way to bank this price indefinitely by purchasing Gift Cards. These don't have an expiry date and as such you can stack up as many as you like to keep you going for the year ahead (probably a method a few eBay scalpers are already adopting).
You can even set the gift card to be delivered to you in the future so you don't have any worry about losing the code.
The only slight inconvenience is that you pay now and you can only use the code on a new account. Other than that, it could be a great way to save a significant amount in years to come.
