NOTE: We have noticed the significant increase in demand for our 450 BM specific products. Often these items sell out very quickly, and very few customers get the opportunity to actually place an order on line.

Subsequently, we will now accept back order purchases of 450 BM products, when your order is placed, your credit card will be charged and your position will be secured. All back ordered items will be shipped in the order they were received.

If it takes longer than 30 days to fulfill your order, we will be happy to provide a discount code for 10% off of your next order. If it takes longer than 60 days, we will provide a discount code for 20% off of your next order.

In the mean time, we are increasing production to keep up with the demand. We thank you for your patience and support.
