Buying from sellers in infibeam

For items in infibeam, I see a section saying something like from sellers and the prices there are generally lower than the item price in infibeam. So if we buy the item from that list is it as safe as buying from infibeam main section itself.I could see that there is COD for such items and they usually take longer to ship.But it is acceptable to me as long as they ship the item in the mentioned number of days..
