Can you get a laptop for 300 euro at Media Markt?

A good one where you can surf the internet

Certainly on the internet, but not a good one or nothing for gaming.

Good and 300 euro are 2 things that are mutually exclusive. However, you can certainly surf the Internet with the cheapest notebook or laptop.

Realistically, you can get new laptops with reasonably good processors from a maximum of 500 euro (and by that I mean that the website builds up in under 30 seconds)

If you have a budget of 300 euro, you should be looking online in the used sector

I'm looking for a new laptop where you can only surf the Internet and that should be available from Media Markt

Then you can actually buy any laptop at Mediamarkt, but I wouldn't buy a laptop for just googling, but a tablet.

How much does tablets cost

Different, go to the Mediamarkt website and search for the Samsung Galaxy Tab A.

But I would like to download series from the Internet and transfer it to a smartphone, you can also use a tablet

I can't tell you that, but how about Netflix? A tablet is a cell phone only in large size so why not look at a tablet?
