That is a fine strategy overall in my opinion. Your best bet is going the WSO route to pick up a buyers list quickly...

In general though, I would suggest putting together more traditional products as it will be much easier to pick up affiliate traction with a big product. I would also do an OTO as well, yes. The difference between a WSO that sells 50 and one that seels 1500 or much more isn't really that big. It's just a matter of doing things right and paying attention to details. I would rather spend a bit more time doing a product that pulls 2,000 sales than trying to do 10 products than each pull 200.

Just my opinion.

But yes, price at $7-$9 start and dime it up to $9.95 or the 14-17 range! Just my personal opinion...best of luck
