Hi Yusif bey, as per my previous message Orkhan Mejidov would like to explore an opportunity to re-sell and distribute your products among his clientele. He would like to obtain preferred customer pricing for engine oils for now. I set L as unit of measure, but he suggested packed goods in 1 L or 5 L to start with. I just thought providing pricing per L is easier at the beginning. When you make proposal you can chose products from your catalogue on Sourcezon and just enter pricing. We have downloaded all your products to your catalogue. Regards Elshan
