Do any of you pre-order gear (amps, git, etc)? Any pros/cons to doing that? What was your experience in doing that?

The Yamaha THR10C amp is being released in the USA 02/25/13 and so chains like Musicians Friend, Music 123 and Guitar Center are saying they will have them by that date for $299. I have a severe case of GAS for this amp and wanted to know what you all thought of ordering the amp pre-release? Thanks.
