Did you receive a Price Increase email from your supplier? If no, maybe it's just on the way, because the raw material copper cost increased 40% from Nov 2020 to March 2021.  

So for any purchasing plan of Pixel led or strips, please kindly arrange it in advance to help you save the cost. NEWSTAR LED produce LEDs by ourselves and we kept enough raw materials in stock, currently our price keeps same, but if raw material cost is going higher again, we'll have to adjust the pricelist accordly. 

We are very appreciated for all of our customer's support in 2020, even it's difficult time, we are growing up together.
