I have been working with ecommerce fulfillment center for almost 7 years now, they are very professional, flexible to work with and always willing to learn new things from you. They also offer great customer service which is hard to find these days! Nothing really at this time but if there was something that would make us want to leave them it's their price structure. We run an online store selling products like fashion clothing and accessories, we used to use another provider who charged too much per order so we switched over to ecomufullfillmentcenter about 8 months ago and since then our business has grown tremendously.
