How do you sift through the noise for good buys?

For me, finding good buys requires sifting through a ton of noise on a regular (daily?) basis and I suspect there’s a better way to do this, e.g. using software to surface potential opportunities.

1. What noise are you sifting through and how often?
2. How have you reduced that noise over time?

Might help the group to mention what bargains you're looking for and how you're going after them.
