Customer: replied 3 years ago.

okay, how do i choose the price?

I think when you post new questions in a new forum thread there are prices you can choose from or I think you have the option to set your price.

 

By the way, have you rated my answer yet?

Customer: replied 3 years ago.

i just did

It just came through, thanks.

For new posts, you can always set or name your price.

Currently, there is no fixed price required when you post a question.

The experts will actually negotiate with you in case the price set is a bit low.

If you need further assistance in setting the price in your question, you can always contact the customer service.

Thanks.

Customer: replied 3 years ago.

Hi, I am not sure what is wrong why you cannot start a new thread.

You will need to post the details of your new questions in a new question posting.

Kindly ask assistance from customer service with that issue.

Thanks.
