Here is a quick little guide on how to buy GME(gamestop) shares quickly and easily in the uk. There are two brokerages i would recommend, Freetrade and Trading212, i will add a sign up link to both these websites giving you the chance to win a share!
First step is downloading the app (make sure to use the link for a freeshare from each company). Once you have signed up you need to deposit some money, only deposit what you are comfortable with, I first started with £150 and have gone onto deposit more.

One thing to note is GME on freetrade is behind a paywall of £9.99 a month, but there are thousands of other companies, ETF’s and REITS to invest in. Freetrade plus does come with its perks, you can earn 3% interest on uninvested cash, stocks and shares ISA and thousands more shares. I would only suggest getting this if your were investing 5k or more, as it would eat into your profits.

Both apps are very similar to operate, go into the search bar and choose how much you want to purchase and there you have it you have bought your little part into GME, it has taken a little bit longer for the sale to go through as it has been in such high demand.
GME has seen some massive swings over the last few months and has been either a get rich/poor quick stock. The whole saga has proved there is power in numbers, and some people/companies(hedge funds) will go to extreme lengths to make sure they end up in the green. The controversial decision to stop people being able to buy GME has really shown the true colours of some companies and how much power big money can hold.
Tips when buying such a volatile stock include setting your buy and sell limits as the price was jumping up and down so much, only invest amounts you are comfortable with and have fun! GME has been a fun stock to get involved in and will be interesting to see where it goes from here.
This is not investment advice, just showing how to buy the stock, always seek professional advice when investing, as a rule of thumb stay away from extremely volatile stocks.
