Tutor: None Selected Time limit: 1 Day

My friend just gave me her promo code and I signed up but It shows that I have $0 and she also has $0 on her account? Can someone help me? Why did I not  receive anything?

if you have already used up a promo code. you won't be able to use again.
you can try with my promo code : Ravi S.

Message me if you still don't get it.

I just tried yours and its says invalid promo code. I tried my friend's promo code again and it said I have used a new promo code but no money shows up on my account?

have you used a promo code before?

Feb 8th, 2015

No? I just made my account.

carefully enter :  Ravi S  

i am not sure why it shouldn't work, many students have used my promo code.

Ok I got it now! It worked! But why did my friend's code not work? Can she enter my code to get $10?

I am not sure if yours will work, but you can definitely give her mine.

I already did give her yours. Does it only work if she is new? She has had the account for a few days now.

It did not work for her.

if she hasn't used any other promo code till date then it will work.
