I think that's the driving force behind a lot these purchases. I found out early on, that this can be quite addictive if you let be. You find yourself reading about what a lot of guys are using, and you want to be a part of that. I'm sorry, but that's the truth. I'm not directing this at anyone, because I am guilty of it too. The only reason I broke down and bought P21S 100% (Normally around $50/tub) is because AG was running a P21S special package sale. I would pay the money for Souveran, especially if AG was running another BOGO for it. I also wish I had jumped on Fuzion when it was $99, only because you get one free refill and I'm sure it's a pretty decent LSP.
Detailing is very much a "keeping up with the Jones'" for a lot of people, and to a certain degree I'm guilty of this as well. I'll put it this was though...I still wouldn't buy Royale/Solaris even if I could $hit $50 bills.
