the advanced sets are great, lifetime warranty, it breaks u take it back, only thing thats not inluded is the ratchet in the actual socket, but then its a wear and tear item, you can get replacement internals of those anyway.
used to work for halfords the only thing that people ever returned were the breaker bars (and the ratchet) and u knew they put a scaffolding pole on the end, still replaced it anyway.
u cant get discount then a trade discount, the trade discount overrules any offers. trust me i tried every which way to try and get more money off. chances are it was a discountinued set.
and yes standard halfords tools are dogsh!t
