I have had a quick look on here and it seems that none of you were watching Dragons Den a few days ago.
There was a company on there that has created an app that brings up voucher codes for whatever website you are looking at. I am not sure if the companies have to sign up to it but I am already using it. For example, I just looked at beauty website and it gave me 2 available voucher codes.
If you download the app, it looks like a Pinterest button, it highlights any available codes for whatever you are looking at.
I don't work for them. Just trying to be helpful as you lovely people have given me loads of codes in the past.
