Great idea but I suggest lowering the price to $2.00-2.50. I think the resulting volume would more than make up for the difference in the retail price, unless there is some sort of associated cost per download FSM has to bare that would make a $2.00 price impractical.
For myself, I'd spend $4.95 for a particular article and that's it but I'd also spend $10.00 if I could get 4 or 5.
