Dear ashishindori,
In reply to your post, we do understand your concern on your bid not reaching your expected price. Please note that when you list an item under Acution with the Buy It now Price, the Buy It now Price is visible to buyers only until a bid is placed on the item. As soon as a buyer bids on your item the Buy It NOw Price disappears and the listing continues as a normal auction.
To minimise your risk on your auction not meeting the expected price, it is advisable that you use the "Reserve Price " feature available in your Sell Form.
To know more about Reserve Price, please click here : http://pages.ebay.in/help/sell/reserve.html
Trust this answers your concern.
Warm Regards,
Tanya Goel
