Sometimes, size matters. Besides prices, you need to check out vendor policies. Restocking fees, return policies, and tech support vary widely and should be part of your purchase decision. Only you can decide which factors are most important and weigh them accordingly. Here's what you need to know to get the right deal for you.
Some vendors only accept returns if the product is defective.
If you return the product because you don't like it or change your mind, you may have to pay a restocking fee, up to 20 percent of the purchase price. Before you buy, make sure you clearly understand the vendor's return policies. Support may be available only during the work week or include weekends. Check each vendor's policies carefully and evaluate them against your situation. For example, if you're not sure whether you really want the product, consider buying it from a vendor with long money-back guarantee and no restocking fee, though you may pay a higher price for the product.
