Hot on the heels of its 500 Avios sign up bonus, the ever-useful topcashback.co.uk is currently offering a £5 Amazon voucher to new users. As we’ve said before, Topcashback is vital tool in keeping your travel spend to a minimum.

Whether it’s air travel, rail travel, hotels or even rental cars, Topcashback is a great way to earn money back on spend you would have made anyway.

Topcashback is of course free to use (although it does offer a paid-for premium service, which is worth considering if you’re a heavy user – I am a member), and to the extent you do ensure you use it for things you would have bought anyway, it is a really good way of getting further kickbacks on any good (or indeed bad) value travel that you buy.

What’s more, sign up using this link before 10:00 am on 22 February 2016, and you will get a bonus free Amazon voucher for £5 when you reach £10 in cashback. To be clear, there is no limit on when you need to have made that £10 cashback by, you just need to ensure you sign up by the deadline.

So who is on Topcashback?

The Topcashback merchant selection is now pretty enormous. Travel related options on there are plentiful, and include:

• Accorhotels
• BA (albeit not very generous)
• Emirates
• Etihad
• Flybe
• Gatwick Express
• Hilton
• Lufthansa
• Qatar
• Virgin Atlantic

Exact cashback rates vary, but are certainly worth keeping an eye on. Hilton has in the past crept above 20% for example – that’s a phenomenal rebate on your stay.

Indeed, it’s not an exaggeration (ok it’s a slight exaggeration) to say that I have made a small fortune in travel-related cashback through Topcashback. While that is, of course, a good thing, it worries me slightly as to just how much it means I’ve spent on travel in the last few years…
