Can led chip manufacturers sample charge be refunded if order is placed?
For Zhongshan Tranch Optoelectronics Technology Co.,Ltd, we'd love to refund the charge of the led chip manufacturers sample if customers place an order. Honestly speaking, the purpose of sending samples to customers is to help you try our product for real and know more about our products and our company, thereby, relieving the worries about the product quality or performance. Once customers are satisfied and willing to cooperate with us, both parties will gain huge interests as expected. A sample functions as a bridge that connects both parties and is a catalyst that boosts our cooperative relationship.
