Topcashback claims to have 10% cashback on HP accessories (here's my referral link if it's allowed... TopCashback.co.uk: The UK’s #1 Cashback & Vouchers Site )
So in theory you'd get 10% back on the ex vat price (£291.67) if the discounts stack for a total of £3218.32 incl vat for a 48GB VRAM card from the last generation. If the cashback doesn't stack, then £3509.99.
Considering 5090s on Amazon are that price for 32GB VRAM it's an OK deal.
