Text Link Ads has recently announced their newest feature called the "HotList." The Text Link Ads HotList will allow you to save (in a list) any inventory that you find interesting. This allows you to save items of interest without actually having to add it to your Text Link Ads shopping cart.
From Text Link Ads, "You will see the HotList icon when browsing our marketplace after you hover over the “reveal” link of a listing."
To note: Text Link Ads is also offering a 15% discount on any new ads purchased and the discount is good for the life of the ads. The coupon code for the 15% discount is: hotlist
Text Link Ads has consistently been one of the best-performing programs for many bloggers (myself included), so I definitely recommend that you give it a go.
