How do you get free roebucks on robloxs

It's not really hard to get FREE robux... All you have to do is go on everyday, well until you have alot of tix. Then go to the catalog. You will see one your left-a button that says "TRADE CURRENCY!" You click that. I'm sorry to say but, to get free robux, you have to exchange tix to get the free robux. Write the amount of tix you will exchange.
10 TIX = 1 ROBUX
I know that's a rip-off but it's worth it. I spent 450 tix and I got 42 ROBUX! RIP OFF!

Thanks for reading...hope this is useful.
