Looks like the two sites differ in price in both directions, some things are cheaper on bass junkies, others are cheaper on scoops link.
LCCA - £136.66
Bass Junkies - £129.00
LCCA - £428.29
Bass Junkies - £499.00
I suggest you find what you're looking for then take a look on each of these sites and see which has it cheapest. To give you an idea how cheap these sites are, halfords has that kenwood head unit for £200.
