Looking for a couple of ex demo kitchen units

I can't find any recent threads suggesting good places for ex demo or inexpensive kitchen units, hence my post. Can anyone suggest anywhere please? We are on the south east edge of Sheffield so Sheffield, Rotherham, Doncaster or Worksop are suitable areas.

We are looking to put a sink and a few under counter cupboards in an outbuilding so we don't want anything fancy or to pay too much. We are looking to buy; a 3m worktop, stainless one and a half sink with drainer, taps etc, one, 1000mm cupboard and two 600mm under worktop cupboards. Not too fussy about design but something easy to wipe down and keep clean, not white or high gloss as that will show up scratches easily.

Wickes do cheap off the peg stuff in a range of designs. You could turn up in a van and take all of the above today.

Thanks, we have looked on line at Wickes and B&Q. We will probably go out and have a look at the weekend. Hubby has to take old units out and give it a lick of paint first.

Thanks. Will take a look.
