Bosch PSB 1800 Li 2 drill with 2 batteries, 241 accessories and toolbox case. Add the cheapest product you can find (e.g. a 69p radiator key http://www.wickes.co.uk/Wickes-Brass-Radiator-Key/p/421534)
to get the total over £100 and use code BLACK20 to get £20 off, bringing the drill price down to around £80.
Code ends on 6th December.
Drill with 2 batteries can be found for around £69 so for me a tenner more for the accessory pack and toolbox makes this a good deal.
