I saw that website on HUKD yesterday and had a look.  It looks similar to a shop that is in Morecambe which we call the cheap, cheap shop! lol.  It's next door to B&M bargains, which we call the cheap shop lol.  
I am going to have a good look at it to see if I can stock up on things.  It's nice to know that someone has actually used them and have had good results.
