Stair Parts USA

We ship items for stair cases that can have USPS Priority mail to UPS ground to LT L freight in the same shipment from different locations across the USA. I came to Shopify after I had started working with Advanced Shipping Manager. This system has made it so we can truly automate our online store and be able to calculate shipping costs. No doubt I kick myself for not finding them 10+ years ago to help with this problem. RIch Burkhart www.stairpartsusa.com
