WordPress Website Design Review from Michael Hamilton
Digital Silk was an exceptional partner in the design and development of NeuroAnimation's new website. Their team was very responsive and worked hard to accelerate the project to fit within a tight timeline. One thing that stood out while working with Digital Silk was the effort they invested in understanding our very unique business. They approached the project as though they were part of our own team, taking care to learn important details about our work, and that dedication was reflected in the quality and content of our new website. We are looking forward to continue our relationship with Digital Silk and would highly recommend them.

eCommerce Review from Greg Meade
Dillon has been amazing to work with. Flexibility is great for agencies, and that is what he offers. We get to work hand in hand with Dillon personally to go over our account's growth and health. He does meetings during times that work best for us as well, and is very good at communication.

Been using them for nearly 5 years. As a UK based seller I've found them to be an efficient and responsive 3PL. Zack is worthy of special mention - his understanding of the mechanics of FBA, his efficiency and can-do attitude has made working with Marketplace Valet a pleasure.

Horrible experience ordering 5.11 tactical pants through Amazon. The pants took more than a month to finally find out the delivery service used Canada post. When they were already on strike. They just blamed Canada Post instead of looking in the mirror. Amazon was amazing and issued a refund immediately. Will never deal with these guys again so be leary of these people. And I see they are still blaming Canada Post. Maybe they should be more in touch with National happenings in Canada!

Been working with PromoShop LA for several years now and they never disappoint. Their team is always quick to respond to any queries and are extremely fair. Pricing, delivery, product quality - all top-notch. The real game changer though is their creativity. They've got some fresh and unique ideas for promotional items that have been a big hit for us. Highly recommended if you need quality and creative promo stuff.
