I have two products, both for the same market. They are on a similar topic, but one is a book and the other is an audio CD. In your experience, should I sell both on the one site or have a different site for each but offer a special deal of the other format?
The theory is that every sales letter should sell only ONE product. It’s OK for the product to be a bundled product, but in that case, the bundle should be the only thing they can buy. Don’t give them options.
Personally, I would bundle everything you’ve got into one package, and sell that package at a bargain-basement price (even if you’re selling it at cost or even below cost).
The bad news is that I think it will STILL be difficult to sell it – that’s just the way it is with selling on the Net. So keep the price low and fine-tune your advertising and sales letter. After you’ve got them working OK, start raising the price.
