I admit to doing that, my CurleyTail 2.0 (Four Seat Flying Pig) is priced at L$299. Why? Because your average person (yes, we have those in SL) are more likely to go for the lower number.
But no one really wants one of those beasts, so it's no biggie.
I'll be pricing my Follow Widget accordingly too. $49 so you don't have to try and walk in a laggy area trying to keep up with someone.
