I have used the Interparcel Economy (UPS) delivery for two or three years now shipping guitars in and out. Overall very happy with the service with most parcels being delivered next day. Recently however I had need to send an empty guitar case out for someone to ship a guitar back to me. I only had an expensive Takamine case I could use. In short the virtually indestructable case arrived trashed.Claiming was difficult and they put obstacles in the way all the way through the claim process. Luckily I view things like this as a challenge and the harder they tried the more resilient I became. They did pay out begrudgingly but if they take the insurance money they should pay out. It has soured my opinion from a 5* to a 4*.
