Fast collection, easy tracking. However my parcel sat in the depot in Houston for 2 weeks before finally being delivered after I complained. It was the first time I’d sent anything to the US and Interparcel did not help once the parcel had left the UK, they just gave me a link to the US carrier. I also found the documents difficult, you have to put in 3 lots of the barcode and delivery details but they have to be accessible, perhaps there should be some way of providing international posters with something to do this by, a clear folder/envelope or something.
