Nutsac discount

I'm about to purchase the Nutsac Tacsac 13, along with the organiser, laptop insert and cable tidies. All in £400. I can find 10% discount. Has anyone ever seen greater discounts for Nutsac or is that the most? On their insta their black Friday deal last year was 10% too. I'm just trying to figure out if it's worth waiting for a better deal...

Thanks baggers
