USPS is the least expensive for the best delivery (priority 3-day). Now that the election is over and all of DeJoy'd shenanigans have been rolled back they are operating smoothly again. I ship a lot of golf equipment all over the US and have had zero issues with USPS. UPS ground is slow. FedEx is expensive.
Sent UPS. 66 bucks. 2 boxes to Texas, one to Seattle. It was easy to do. Walked by post office, line was out the door.
