Online quotes for computer repairs are sometimes accurate, but generally, a user won't know the exact cost of repairs until the company has the computer and diagnoses the system. A quote gives the user an idea of the average cost of a repair.
Once a person sends in their computer to be fixed, it's at that point that the company can give them a full, accurate quote. The new quote will state exactly how much the repair will be, helping users decide if the computer is worth the expense. Sometimes, the quote is higher than the initial repair quote, and other times, it may drop if the problem with the computer is less severe than expected.
