wow this is getting very trivia, if you not happy with the decision of OCUK b grade then go and buy the full retail, as they said nothing in life is free, if you see the price is reduce just take it as sometime major could be missing, and if you get everything in the box minus the manual who gives a kick especially is you have save 30-45 pound or even 10-15 pound............... for example a graphic cards what would be important the main item or the connectors and Drivers????
Treat the item in B-Grade like ex display, what you see is what you get, in the sense of the main item is there and maybe some bits.....my person view i would say b-grade would be for people who is looking to replace the same item, if i am incorrect Don please correct me.
