急what is important when looking for a new supplier?

If i am in market for some new products,and i am looking for a supplier,i will take these three factors into my consideration.
First of all,quality.It is the life of the product.Price and quality are closely related.if the prices (or we should say discounts )are reasonable,or acceptable,and the quality is good,then i will choose the producer as my supplier.More discounts do not necessarily mean good quality.No quality,No market,but No reasonable price,no profit.
and then,the next thing i have to take care of is the delivery times.on-time delivery is very important other than the quality and discounts.We have products of fine quality and reasonable price,but if we do not have the on-time delivery,we can not put them into market at the right time,then,it means nothing.we will lose out.SO,delivery times are important.
So,good quality at reasonable price with on-time delivery comes first.
