Simple pricing

Pricing doesn't need to be complicated. Take the cost of the stamp, 60p for First Class, 50p for Second Class, then for colour add 25p for the first page of your document, and 15p for each subsequent page, for black and white add 15p and 5p for each subsequent page.

Fully Automated Dispatch

Pay As You Go

Top up your account from £1 and pay only for what you use. Auto TopUp ensures you don't run out of credit by topping up by a specified amount when your balance is low.
