Neopets Cheats Free Neopoints?

I have no neocash and i want my neopet to look nice!
Any good neopets cheats that get neopoints?
If you have any cheats to get alot of coins that would be awesome. I play neopets all day but haven't tried any cheats yet, my friend told me there's a cheat that make you earn neopoints. What's that cheat about?

Some sponsors get their own page on Neopets, and you can visit these sites and earn free neopoints! Some you can visit once a day, others 3 times a day, and others even 5 times a day! And we are not talking just 1 or 2 extra free neopoints here – some give you as much as 500 neopoints each visit!

That's how I get free neopoints in Neopets.

What websites?
