Most of the time they are a very quick cost effective way to send parcels. The quote and booking system is very clear and simple to use and you can save addresses for quick retrieval the next time you want to book. My only gripe is that they've lost 1 parcel and delivered another to the wrong address over the last few years and I have had to pester them for help and answers, with some of the operators cold phone manner clearly indicating (in my opinion) their annoyance at having to follow up on problems once they'd had my money. Eventually it became non-cost effective to pursue the problem parcels and my company gave up. On principle I shouldn't use them but the money saved on their great booking system (for me) outweighs the occasional loss.
