Just brain storming here:
Joe has a good point about the web page looking like the magazine add. Also, I've seen the Media Kit from Dragon Magazine. Like other magazines, it is cheaper to buy long term ad space than short term space.
So why not buy a smaller space (1 page or 1/2 page) over a long term and have it "link" to a discount sales page like you've done, but make that page resemble the print ad as much as possible.
also, you must ask yourself, who are we trying to recruit? Gamers who don't shop online, or online shoppers who don't game?
RPGnow distributes everything a person needs to play d20 as well as dozens of other games. Plus, RPGnow sells short stories and some software.
What about working the software angle more? Software is the future of RPGs, if you ask me.
Also, in terms of recruitment, it is my experience that the only people who buy stuff at RPGnow are fairly "hardcore" gamers. Perhaps 1 or 2 out of every group shops online (just a guess). The others are aware of it, and just don't do it.
Why?
Shopping online is a barrier.
However, people who already shop online might be easier to convert, especially if RPGnow offers a variety of games and software.
To that end, I'd look to advertising on places like the SCi-Fi channel web site. E-bay isn't a bad idea. AFAIK, retailers can sell on E-bay. I'm not much of an online gamer, but I'm sure there are communities for x-box type groups and I know I've seen plenty of EN-world type communities for various computer based war games.
Also, I haven't seen the dragon ad, but I know that there has been a discussion recently about the benefits of PDFs. I believe that most people don't buy them because they don't understand the value. In a discussion on the RPGnow boards, I made a list of these benefits of a PDF. Perhaps telling people in the ad exactly what the benefits of PDF s are, is a good idea.
BTW, the benefits of PDFs are:
1. Immediate Delivery. You can find it, buy it, and get it delivered to your hard drive without getting out of your chair.
2. Minimum Shelf Space. Even the biggest e-book files only consume a small fraction of space on your hard drive.
3. Functionality. E-books can be equipped with hyperlinks (both internal and external) that make finding certain material much quicker and easier than flipping pages in a printed book
4. Potential Updates. The E-book format is easily updated and revised, so when you buy one you usually also get all the subsequent upgrades and revisions for free.
5. Replaceable. If you buy from RPGnow, your file can be replaced if it gets lost or destroyed. Obviously, if a printed book gets lost or destroyed, you can't just contact the distributor to get another one.
6. Cut and Paste. It is easy to select certain sections of an e-book, cut them out, paste them into a word document and print them as a personalized, specialized, collection of material. Doing the same thing with a printed book would require an optical scanner or a lot of time typing.
7.Durability: Being an electronic document, it never suffers from wear-and-tear.
8 Price. Since e-book distribution cuts a lot of the overhead costs, an e-book can be sold at about half the price that the same book would cost in print format
