Just letting you all know that for the next 24 hours Amazon is giving all its customers £10 off a £50 spend or more. I just bought a WD 4TB hard drive for £90 to back my music up and thought it was worth sharing.
Promo code - BIGTHANKS
Happy spending 
It’s actually BIGTHANKS according to their website
Haha! BIGTHANKS for pointing that out. It got the message across at least.
I’ve edited my original post.
Just grabbed a 3TB backup drive myself - you can never have too many backups! Thanks for flagging this one.
