My experience is very bad with MYUS, I was waiting for an urgent packages and I had used FedEx Priority for shipping, the problem is that MYUS took 2 days for package acknowledgement and another 1 day for reviewing merchant invoice then the worst thing they put my account on hold for review and they release it after two days I wasted 5 days due to their poor system to deal with customers, I paid lot of money to ship in 1-4 days but I received by 10 days, so I advice every shopper to look for another service provider
