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!
