Saw these in a basket in Poundworld in Bishop Auckland today - probably nationwide - as advertised with a professionally printed flyer.
Boxed Pregnancy Testing Kits - some of them were packaged as 2 for £1.00.
Looked like a decent make but ..hey I'm no expert. Big saving on well known brands which retail around £10.00
Instore only and sorry no picture - didn't want to get arrested photographing these items.
