HI Archana,
I think 100bestbuy is a good site to online shop. They provide exiciting offers for the users and that it is really awesome i hope because recently i got a mail from them and i joined in that web site. They offered me products for free and they asked for me to pay for shipping charge only. I was asked to pay Rs. 250 for shipping and they said that it was Sony I Pod and they shipped some other product which was a great cheating and i thought that i lost my money. Then i returned the product to their address as they mentioned me in their replied mail. Suddenly after 12 days at evening a courier came and it contained my new Sony I Pod. At first i didn't beleive it but now me fell very happy and excited. Thanks.
