Bit of a strange one this but here we go;
On the shelf they are marked as 25p + 20% VAT. But apparently there is a 25% off on all cable's at Makro so they took off 12p from the two I bought for 25p a peice, making it 38p for two or 19p each, then they added the VAT. So 19 x 1.20 = 22.8p each.
They are just standard HDMI cable's, not gold plated.
No idea if it's national or not. Was in the Middlesbrough/ Stockon shop.
