Large electronic stores may offer special discounts is you decide to purchase your complete system at their store. Retailers often include additional free software packages with a computer purchase. These offers can make the retail stores quite appealing. Also, it is important to know where the computer can be taken to be serviced. Many retail stores may have a great service department to help with any troubles down the road.
Warranty is an important factor in purchasing a computer.
Not every store or computer company will offer the same return policy. Also, check to see if the store requires the customers to cover restocking fees. Try to avoid this if possible. Some of the better companies will offer a three year warranty on parts and labor. This can be a lifesaver if after six months, the system decides to die.
