Yeah - I think this is quite widely acknowledged. Farnell/Newark route does offer a significantly wider range and often more extensive product information. Targeting different markets eg CPC have a focus on seasonal consumer goods eg Xmas decorations and fans/heaters.
And CPC have a lower threshold for free shipping.
I have actually seen a product costing more at CPC but that is rare.
CPC "Bargain" listings always worth a look though not so good lately.
