They have camping gear in next Monday: www.lidl-pageflip.com/uk.html?kid=ZaMsPn
Including:
4-shelf camping cupboard for £35 (looks to be exactly the same as the Hi Gear one from Go Outdoors which is £40),
5x4m tarp which would be good as a footprint for £8
Double 5cm SIM £25
4.5m shade sail £30
lots of useful stuff (you've probably clicked on the link by now so I won't list everything)
