I want best price for 500 pairs of mens dress socks. I want my designs to be placed on the socks using sublimation, as well as my logo. I also want to know if you do drop shipping to USA. I will be having socks made in China then sold through my Shopify.com website, then each order shipped directly to customer. I want to know if you can do this, or if vI have to use a warehouse in USA to ship socks to customers after they make purchase through my website. Before I buy socks I also need to see completed sample. How much for sample to be sent to me? I also need to know if you can provide packaging with my logo as well.
