The Internet is a dynamic market place. Internet stores often run sales, and specials. I will post internet sales and coupons of note on this page.
Many of the sales use promotion codes. To use a promotion code, you need to copy the code into your computer's memory (ctrl-x) and paste it into the promotion code box in the check out screen (ctrl-v).
You can open the sale event in your browser by "right-clicking" your mouse on the link and choosing "Open in a New Window." The stores page shows all online coupons for participating internet shops.
