what care to take for online shopping?

The online shoping is not trustworthy. You can not be sure about quality. Even if manufacturer is reputed, agents who do the marketing part, could cheat you from faulty piece. Moreover if you are to pay through the credit card, Please don't do that unless you have installed a sequrity software which checks the spyware, malware & trojens residing on your hard disc. If you have installed it after few days of your usage on to internet, then also this danger exists. As soon as enter the credit card information and the password, everything is sent to the devil hacker. And you are GONE! Forget the quality or benifit in shopping online, Your credit card will ask you for the maximum limit of you. You may find large amount outstanding in your name!! You understand me? uttam uttar aahe ki nahi?

You may be surprised at this but I have bought cars - twice - without seeing them in advance. And there was no problem at all. I do a lot of shopping on eBay etc and that is fine overall.
