I have a bag to ship from the US to the United Kingdom. The buyer wants me to ship quickly rather than getting it USPS priority international. (I think that is 6-10 days.) I called FedEx and they want over $120 to ship the bag. (It's 4 lbs and is a MC LV Speedy so rather large box...11 x 11 x 14) I think I remember a thread about this but it's been a long time, maybe last summer. Is USPS Express mail better than using UPS? I was going to use USPS but just can't remember which carrier is faster and less expensive for the buyer....and reliable! Thanks.
