In our fourth deal of Christmas we’re giving away these wearable LED headlights.

To get yours just use promo code COMET at the checkout when you buy any physical book.

These LEDs are just the thing to light up your outdoor exercise sessions, particularly on a cold winter’s night or morning.

The only sting in the tail of our comet is that stocks are limited, so hurry and order now to avoid disappointment.

In addition, HK Rewards Members get a rather splendid 20% off all their purchases and a free eBook of any printed book they buy*.

There’s also free delivery on everything to the UK, Europe and the Middle East.

Don’t forget our previous deals will still be running right up to Christmas, so if you’d prefer a different offer, just enter the relevant code instead.

Details can be found at the bottom of this page.

Only one code can be used with each order, the choice is yours.

This offer is only open to UK, European and Middle Eastern customers only.
Please read our full terms and conditions.

*If an ebook version is available.
