Seasonal and retail vendors of rawhide at the Kalibari market under Palashbari upazila are set to incur huge losses as the price of the skins they collected during Eid-ul-Azha has fallen drastically amid low demand.  Although they collected the rawhides of cows and goats slaughtered more than two weeks ago, poor purchases and sales were still noticeable on the last market day, Saturday.   Vendors brought their stocks to the largest rawhide market in northern Bangladesh but buyers were not in the mood to make bulk purchases, upsetting many vendors.
