There is generally a page-wise or question-wise pricing and the price is fixed for a particular question. If you want to save some money on your accounting assignment, then you have to send in the assignment request 1-2 weeks before the delivery date. This way you can save some extra money. There are also offers and counts on most of the websites. If you don't like the assignment or if you think that the quality is below par, then you can also ask for a refund.
