Hi Duggie, The Amazon store are direct from Lexus, I have done a quick price comparison and it looks to be the same as their eBay account, some items we are cheaper and some they are cheaper.
Here is an example for LS Rear Brake Pads
Amazon: £114.99 https://www.amazon.co.uk/LEXUS-Genuine-PS506H-1994-2000-0446650110/dp/B09MWKYC32/ref=sr_1_15?m=A231AEWPY4RM1A&marketplaceID=A1F83G8C2ARO7P&qid=1642092946&s=merchant-items&sr=1-15
LPD : £86.95 https://lexuspartsdirect.co.uk/product/lexus-ls-phase-2-rear-brake-pads/
Plus we are nicer 😛
