Another important purpose of express delivery is to simulate a total price (incl.shipping) from those notorious low-ball New York/New Jersey web sites (See point 1 on this page ) with our standard shipping on some shopping comparison search engines. Then we add the express delivery surcharge to provide a contrasting experience: we will ship to your destination in 6 business days, long before you would have any clue as to where your order is with these web sites except that your credit card would be charged immediately despite the violation of one of most basic rules by major credit cards: no charge is allowed without product shipped first.(A credit card issuer will unconditionally put money back in a consumer's card when a dispute is initiated.) Consumer Alert: Many of the sites that rank at the lowest 20-30 percentile of price (for example, the 5 lowest price sellers out of 20) employ the availability trick. When a consumer does not order the "add-ons", the order will be ignored in the name of "product no longer available" or "out of stock" until the consumer can no longer wait. This is essentially a modified form of bait and switch because the seller would lose money if it honors the deal that is below the cost.
