Companies are constantly coming out with new products. The benefit of this to you is that you can normally find a printable coupon for it online. You can either google the product name and the word coupon after it, or watch commercials.
The new trend in tv advertising is giving a url for viewers to go too. Many times, there is a printable coupon for a few dollars off or a free sample to be shipped out o you.
Also, the url's might not be the main site, so keep a little notepad by the tv, and just jot the website down for furhter viewing.
The reason for this new advertising trend is because, web views and visits are traceable. The market research teams can see who is coming to the site, what times and if the marketing method is working. You can't do this with TV.
So reap the benefits.
Here are some recent lists I've seen:
$1.50 coupon - Aveeno Postivly Aging
I'll add them as I find them!
