Since buying anything online has a huge risk of fraud and trust issues, I have decided not to sell my paintings on my website. Instead, I am a member of Saatchiart.com which is the biggest online art dealer that anyone can trust. So, if you find a painting that you would like to buy, please send me an email to info@rashidarts..com and then I will place the painting on Saatchiart.com website and then you will be dealing with them and that solves the trust issue for both of us.
They provide you with all that you can expect from a respectable online store (money back guarantee, delivery within a week etc). They charge me 30% of the sale, but that is a price I am willing to pay in order to satisfy a potential customer.
