Want to sell personal gold jewellery in dxb , but i do not have the proof of purchase. can i still sell it? -

I remember the month and year and the shop of purchase, but have lost the bill...also when i contacted the shop, he told me that for selling gold for cash, they will deduct Dhs. 12 from the current price and give me cash..is this correct? does anyone know any reliable place in dubai where i can sell my gold...

Empire Gold pays really good price for gold and Jewelry:http://www.shareasale.com/r.cfm?B=185538��
