I have noticed since the buyout of Europarts and their sister company CarPart4Less by LKQ that there is now often a big difference on prices between the pricing of the two online when you can collect online orders from both at a local LKQ Europarts counter.
Whilst the online headers for EPs often suggest large discounts they now appear very limited and often many parts are at full price. They do not appear to offer block discount codes across a wide range of items.
Currently the system of discount codes is still a feature of CP4Less.
As an example if you order a Beru rotor via CP4Less with the current discount of 24% (SALE24) the rotor comes down by £6.24 from £25.99 to a more acceptable £19.75. That's is my guideline price when looking at the firms I might buy from.
