Frequently Asked Questions
How can you discount fuel?
Simply put, fuel card providers will buy "oil futures" (or wholesale barrels of oil to the rest of us!). Typically, buying wholesale means the fuel price can be fixed across all the supported petrol stations - normally, 4p to 5p cheaper than the pump price.
How long does it take to get the fuel card?
It takes about 3 minutes to apply using the mobile app. You can expect your fuel card to arrive by first class post within 10-14 business days.
How does PostTag make any money?
PostTag take a small percentage of the discounted fuel you fill up with. It's only a few pennies per litre, the rest of the discount we pass on to you.
Are there any fees or subscriptions?
It's completely free to use! You simply apply using the mobile app, use the fuel card when you fill up and pay for the fuel you use.
