Pricing items, no matter what they are, is a science, and it comes down to psycology actually. You should price them at $3.49 rather than $3.50, or $6.99 rather than $7.00. That small penny difference makes a huge difference in the mind of the consumer. That's why the Big Stores use such pricing, it makes the item seem like a much better deal. If you price them right, and they are amazing as I read about here, then you will do very well I'm sure. I hope this helps.
