Hi, I am trying to find the most efficient company to handle my shipping for my business. I do a lot of shipping, but couriers can be expensive. I have no problem paying top dollar, but I would like to know that all of my expectations will be met. I'd like for my customers to get their packages at the time I supply them with. (I will only promise what the courier tells me) I would like to get a deal for a better price, considering my shipping volume is higher than some other small businesses. Any ideas? Thank you, George.
