In late January 2019, our son came east with his family so our grandson could have his first birthday with us. Awesome. Having family in 2 general locations, we had a birthday party for my side in PA and wife's side in Central NY. Even though the kids asked for gift cards to simply things, many small gifts arrived. So from the two gatherings, the kids sorted what they could fit in their plane luggage. For the remaining we priced UPS, Fed -Ex and USPS. All similar, but USPS flat rate boxes worked out just a little cheaper and had the automatic insurance. So we thought we knew what we were doing. Two weeks later, son informs us it would have been $30 for an extra luggage bag to fly versus the $80 spent on USPS flat rate shipping. At this point we had already boxed the 'Toy Tote' wagon and another box of our son's childhood items and sent them UPS, being assured by my brother, UPS was the only affordable way. The Toy Tote would have been too big for the plane restrictions, so UPS was the cheaper route (compared to USPS), but the other box could have been their second extra $30 luggage bag (1 per adult) versus the $60 spent with UPS. Then came surcharges. Turns out, in many Colorado towns, UPS does not deliver to homes, they go to the post office. If it is too large a package for the post office, it goes to the local UPS Store. The store notifies the post office, the post office notifies the box holder, then they go to the UPS store. So, UPS charges for the additional transportation. One of the 2 packages they charged an additional $36 to return to sender, even though our son picked up both packages. I thought it was interesting that it cost $41.25 to ship out and they were charging $36 to return. So my brother lost another hour today (and 1 last night) trying to get to speak to an English speaking UPS rep to get surcharges defined, and return fee back credited. Really sorry I asked for a favor to ship a few packages. Still not resolved. On a positive, in the future we can send packages 20 miles further west to a bigger town to our son's in-law's house where UPS will deliver, at a cheaper cost.
