I'm sure people have heard this already but Amazon are increasing their Prime fees from 15th September. This is the T&Cs on their website. If you like Prime and can afford the yearly price it might make sense to renew or start paying yearly subscription now:
Amazon terms
The updated pricing will apply to Prime sign-ups beginning on September 15, 2022. For current Prime members (including Free trials), the new prices will apply to all monthly or yearly renewal from September 15, 2022.
Upcoming changes
The price of monthly Prime membership will increase to £8.99, and the price of the annual Prime membership will increase to £95 per year.
For Prime Student members, the price of the monthly membership will increase to £4.49, and the price of the annual membership will increase to £47.49.
Hi Iris, from what I read in the following article you might want to double-check about the getting the discount for the year.
