I can remember a couple of decades ago when the internet was just something available for geeks. Most of us were quite happy using a computer at work, and then going home to watch the TV. Most of the technology that we have today never existed then, and the only way of getting information was the usual media sources, or the printed page, such as newspapers and magazines. I know that I would spend ages going through various papers and cutting out the coupons in order to get some freebies UK. Sometimes it was a case of posting them off and waiting in anticipation for the delivery.
That final fact is the same today, except we can now use the internet to look for free items that companies may be giving away in order to try and entice us to buy their products. I especially concentrate on beauty items, as there is now so much competition around, the brands are falling over themselves to give us stuff. In fact, you do not need to search for coupons, just contact the company directly via email, and ask if they have a sample. More often than not they will send you something.
