Personally, I think that the sabers with sound section is misleading, because they don't include the price of sound in the price listed in that section. For Example it says "Catalyst with Sound $149.00" When in reality you have to update the price before checking out and it goes up that 75-100 dollar amount. It should just have the price of sound included.
Actually that's a pretty good idea. It's something that's confused people in the past, and now that they've separated their stunts (no sound) and sound sabers, I think it would be appropriate as well.
Then again, there's probably some business sense involved in this. If people see a $200 or $300 price tag, they might just shy away. If they see the price of the saber and then add all the stuff individually, they have more faith in the idea that they're actually gettting their money's worth.
