....or you could have gone to the Royal Mail website, paid for your postage - with a whole range of tracking and insurance options - printed your label and had your parcel picked up by your local postman, who gets paid a decent wage, has all the rights which UK employment law requires and whose employer pays NI contributions on that wage and pays something close to its fair share of tax in the UK.
It might be more expensive than other couriers, but that's because Royal Mail are paying for all the benefits that most people expect from their own employers - sick pay, holiday pay, p/maternity leave, pension, but, for some reason, think are too expensive to pay for other workers.
