I'm working on putting together a carbon card product and three volumes of 2 effects each. What's the bulky price? Five...Maybe ten dollars? Each? What would you say if it's all--Free?
Just be as sure as possible that they are all absolutely original. There isn't any fudging going on at all with that stuff. Depending on your product it may be worth a lot. It really depends though.
Sometimes charging more is actually a better way to go. Psychologists will tell you that we perceive more expensive things as actually being better than their less expensive counterparts. So we'll believe a $20 bottle of wine tastes better than the $10 bottle we just drank, even if they're both filled with the exact same wine. Just something to think about...
