This is one of the sites that I visit daily and maybe sometimes two or three times and it is definitely one I visit BEFORE I buy anything online. It is a website where anyone registered who finds what they feel to be a good deal (ie discounted or cheapest price) will post and inform the rest of us of this deal. I have saved hundreds of pounds through this great website and its like I have hundreds of elves all working for me to find me the best price.

The way the site works is people post a deal and the rest of us vote whether is a hot deal or cold, some get very hot when they are an absolute bargain but you do need to be very very quick with these as they are normally that low to get rid of excess stock.
The latest to be made hot is the one that is at the top of the list but you can search through companies etc, If the person has listed it correctly it will be tagged to that store to make it easier to find.
You can also comment on the find (this can lead to people being obnoxious actually but mostly to say thanks its a cracking deal)
Also they can post about supermarket deals such as morrisons and tesco BUT this also leads to people going out and finding that the deal is not in there store but also that we all report back if it IS in a certain store. Most who post have learnt to take a picture of the shelf label to prove the deal!
Posts are made up of the link to the offer and a picture of what it is if possible and a short description.
It is easy to search for an item if you are looking for something in particular and if there is a voucher that could be used then this is normally attached to the post as well.
If there is a voucher for a certain company (eg M&S or tesco etc) then they can also be posted seperately, sometimes they work for all and sometimes they dont but always worth a try I would say.

My advice is always check if you can get it cheaper, find a great cracking deal and make it even better by going through a cashback site such as quidco or topcashback as well.
