I had cause to book a parcel pickup & delivery via parcelforce today. The checkout process was quite good, however, I opted to print the labels, and attach them to my parcel.
Upon paying for my order, Parcelforce provided the label as a downloadable link which ended up being a file called accessor.epl. Now, whilst OS X is very good at handling a multitude of files, for some reason, nothing would open this file. A quick look on Google found nothing either!
However, I renamed the file to accessor.pdf, et voila! Turns out it's a bog standard PDF, but was just named incorrectly - so keep that in mind should you decide to use their service.
I also managed to get 15% off a 24 hour delivery by using the voucher UPAG!
