Question on making offers

[Arthur Fuller II]

@Brandon Turner tells us that we should be making multiple offers weekly. My question is what is the best way to do this? I recently set up an alert on redfin.com that tells me when something comes on the market that fits my criteria - but once something comes up do I simply contact the listing agent and tell them what I want to pay? or should I have an agent represent me and make the offer. And if I do contact the selling agent and give them the opportunity to represent me but give them an offer bellow the listing price and I running the risk of offending them?
