Christos, I have the "special offers" on mine.
They're targeted. It's Kindle related stuff, deals on books, and honestly, I'm happy to have them there. If you don't want them there in the future, you just pay 20 bucks.
But really, it's no bother. See what you think.
Here's how you remove them.

Thomas, you have all that French stuff to read. Recipes or whatever.
You'd really like that Julia Child book with all the food in it, it's awesome.
