Free Stuff on Twitter

Companies are always giving out free giveaways and discounts via their Twitter channels.

Anyone know of any of the best Twitter channels to get free stuff from?

I know Jet Blue sometimes gives out $9 flights every so often via there own Twitter channel (@JetBlueCheeps)

I think they give discounts and free stuff everywhere and anywhere there are takers tbh, not just on one site

Yeah but some of the Twitter channels give you like exclusive content like unlockable stuff in their games, like EA Mobile does
