Last week we looked at two Web portals, FatWallet and CouponCabin, which assist in the search for on-line deals. Today we look at a few issues involved with shopping on-line. Buying stuff on-line is becoming a routine activity for many people. We save precious time and money by doing so. A recent Nielsen survey, conducted globally, found that ...over 85 percent of the worlds on-line population has used the Internet to make a purchase. That figure is up 40 percent from two years earlier. The survey also found ...more than half of Internet users are regular on-line shoppers, making on-line purchases at least once a month. See www.nielsen.com/solutions/GlobalOnlineShoppingReportFeb08.pdf for more information. Many people are concerned about compromising financial data especially in the on-line environment. I agree there should be some level of apprehension because hardly anything works perfectly all the time. Remember a few weeks ago when we talked about the wireless systems that were virtually security-less as well? People who made purchases in the brick-and-mortar stores affected found that, in the end, paying with a credit or debit card in one of those stores was ultimately less-safe than buying through a secure on-line retailer. Personally, I have never had a problem with an on-line vendor who operated through a secure Web page. How do we know if the page is secure? Look for at least two things: the lock icon and the letters https instead of http in the URL (address) of the site.
