Yes, you can ask your teacher to give you an offer in some cases, and it all about his decision, Convrld has nothing to do about that.

1) go to your dashboard 

2) select teachers .

you will see that the lock sign became Red instead of black that means the teacher adds a specific price for you.

3) you can follow the instructions of How do I purchase lessons?

Note: the offer valid only for the same teacher that gave you the offer.
