Picked this set up in Wickes yesterday. Probably not great quality for professionals but should be suitable for all the DIYers out there...
Drill and Screwdriver Bit Set:
A wide range of HSS, masonry and wood drill bits
Plain slot, cross head and pozi screwdriver bits
Also includes hole saws and sanding drums
I think postage is £5.95 if ordering online. They had plenty in my local store though.
