The only common denominator I'm seeing here (Sports Direct and ECP) are that they both sell a hell of a lot of stuff, hence they can reduce their prices.
The branded stuff in both outlets is exactly that...branded. I've never seen Adidas / Nike in Sports Direct much cheaper than anywhere else, its simply marketed better with numerous outlets so you can try it on , quality same as...err....anywhere else ?.
ECP deliver to several independent garages around our way....they have a fleet of vans. My understanding with brake parts is that the garage won't fit if you supply.
As for paint, yep there's a rumour that the stuff they sell in the sheds is inferior quality.....to what and to whom I wonder? Most punters buy paint from the sheds and it does what it says on the tin and that must be 99% of the market so yeah..I just don't get it. .
