Our current lead time continues to increase. The 12 month-plus announcement hasn't made a dent. We continue to sell mirrors faster than we can make them. We're a long-established two man shop, we also run a coating operation for Zambuto mirror owners, and we're not 39 years old any longer like when we started. I'm now in my sixties. We just took a hard look at our backlog and a few small stragglers are shipping at 17 months. We have to quote an 18 month lead time now for all new orders. We refuse to compromise the caliber of the Zambuto mirror, so this is what it takes. A 50% deposit places an order and begins the lead time. When the mirror is completed and goes to our lab for coating, the balance is due. Contact us for more details and payment options. Shipping costs- We ship at the lowest possible rates, at actual cost to us for both foreign and domestic shipping. We use the US Postal Service for international shipment. Mirrors are shipped using Priority Mail International, which is less than half the cost of UPS Worldship, and when the value is above $2,500.00 we use Priority Express International, still at substanstial savings. The size limit for this service depends on destination, as width and girth limits vary by country. Larger sizes are shipped Global Express Guaranteed which is still less cost than UPS. But in every case, Zambuto Optical buys the insurance for you. There are no added insurance fees to ship internationally, only the lowest possible rate to get you your mirror. |
