- Hey dude, you could've gotten that from MSY for 100$ less!
- Yeah I couldn't be bothered queuing for 50 minutes and then finding out that they have just sold it!

- Go to Dick Smith first, talk to their friendly sales guys, figure out what you want, and the get it cheap at MSY.
- Yes, only if they haven't ran out of it!
