Every day, lots of people submit their contact lenses prescriptions to online resellers. The well known retailers receive up to 5000 orders each day. Consumers prefer online orders because they receive same product but for a lower price and with less effort. But how people know which online retailer to buy from when all claim to have the best services at the lowest prices? Read on to discover some useful tips.

    The difference in cost between two different sites can be very high (sometimes double price). This is happening because some sites display the total price including shipping while others display only the price of contact lenses. A good place to start your search is a price comparison site, daily updated.
    Buying discounted contact lenses online, depends on five factors which make a big difference in the total amount that you will pay. First of them is the price of the product.
   
    If you buy the directly from the factory site, you will pay the minimum price per product, while if you choose a retailer or online affiliate, you will pay one or more commissions included in the final price of the contact lenses.
   
    The second factor is the shipping cost. Try to find seller near to your city to pay less for your contact lenses. The third factor is handling cost which means the cost for processing your order. The forth factor is the volume discount. If you buy more products you may benefit of discounts like free shipping, free ordering or price decrease in fixed amounts or in percentage. The fifth factor is coupons or promotional discounts, which are usually available for limited time.
   
    You have to consider all these factors to get discounted contact lenses. Remember that you don't need to buy your lens from a brand-name site, but it is recommended to buy brand-name contact lenses.
   
    Some websites that sell contact lenses online, have spent many million dollars in advertising and now they have to get their money back from high prices. Usually, the most important sites in each niche, sell the most expensive products. There are lots of other sites where you can buy contact lenses, at the same quality but for lower prices.
