No problem! Glad to help. Here's a few tips for staying competitive with people who are undercharging.
-Also give your price in dollars such as: .....400 points ($5)...... This will show your buyers that they're only spending "$5" ...which sounds cheaper than "400 of something"
-Link to this news article I wrote [link] (or write something similar of your own) and urge your buyers to support fair point commissions.
-Whenever you see someone charging way too little for their hard work, give them some encouragement. Saying something like "Wow, you're way too awesome of an artist to charge that little" would probably go a long way. Linking to my article or something similar would also help.
