We appreciate the repeat business, but unless a firm written estimate is provided prior to all shipments, each new order has separate pricing. With both online store stock items and custom orders do NOT assume that your pricing is fixed and you will always receive the same pricing. Our costs and lead times frequently fluctuate. Quantity price breaks for online store items apply only to items shipped at one time in one order. If you need to reorder a smaller quantity at a later date, you will not receive the same higher quantity price break. Any special sorting for color, texture or size will always increase the price. As a rule of thumb the way to get the best negotiated pricing from us is to order in advance and ship as much quantity as you can use in one order.
