Been a customer of Shippingcart for more than 3 years now! Platform is easy to use, they always provide updates about my packages and items bought from US. I never tried buying from UK but planning to try soon. Never had a bad experience at all for the past 3 years.
ShippingCart always delivers my packages ahead of time except if there are unexpected holidays that causes few days of delays specially during peak season, max 3 days delayed based on my experience. Good platform for someone who is teckie person like me. I'm not a fan of manual processing of things like how others do. Door-to-Door delivery is a plus, seamless service. Photos of items are also provided, thus I know if Amazon sent the right item/s they also help in returning the packages if amazon delivered the wrong item.
