KontrolFreek FPS Freek Galaxy Black Xbox Thumbsticks with code

Very good price on the KontrolFreek FPS Freek Galaxy Black performance thumbsticks for Xbox One / Series XS. Currys has them at £6.97, then code ACCESSORY30 takes another 30% off, bringing them down to £4.88.
These use a high-rise and mid-rise combination designed to improve aiming precision and grip. The same Galaxy range is currently £16.99 direct from KontrolFreek, while the closest competing listing I found for the exact Galaxy Black Xbox version was also £4.88 but with £4.49 delivery, making Currys better if using free Click & Collect.
