I went with shippingquest because their customer service is outstanding. updates are given from time to time and billing was even explained well. I understand why the quoted price given to me almost went double. I send out more weight than I estimated during reservation. They gave a good discount and was even able to get extension for the Due date. This is the same scenario with air freight shipping. If you have more weight than you booked for basically you will be charged. I will use their service again and I will recommend them to my family and friend. More power ShippingQuest. Thank you
