Don't get lured into joining prize draws managed by strange organizations or businesses.  Deceitful marketers often employ this technique to obtain prospective subjects. When buying a product online, it's not uncommon to be charged in addition for shipping charges. However, due to the fact different sites or vendors have very different rates, it is advisable to check for the shipping rates first as others overcharge on their shipping rates. There are some vendors who sell an item in full price but bundle in "free" additional items, while you can find others who put an instant rebate or price cut on all purchases. It is advisable that you buy from vendors that don't adhere to the minimum advertised price (MAP).
