Customer service is responsive. However this is the only company I've ever ordered from that took payment from my account before even processing the order. I also have a koi pond cleaning business so I'm constantly trying to find the best prices. While the prices are good, PIK seems more like a middle man for products as they take your money and then place an order with a different company for the processing and shipping of the product. It will be a week before your order is processed and shipped. If your willing to wait a little longer then the pricing is good.
