Subject: Re: Dealraker made a point worth contemplating: "
WEB invested in businesses he understood. For a retail shop, visiting is an easy way to better understand the business. I am not a fan of the DG business model (selling unhealthy food to poor people), and so would never consider investing in DG. I have never been inside a DG, but have been to Family Dollar and Kmart stores that probably are similar. The Family Dollar and Kmart stores I visited are now closed, and have been replaced by higher quality stores. This reinforces my reluctance to even consider a DG investment.

Buffett's 2007 Letter to Shareholders
"Let's take a look at what kind of businesses turn us on. And while we're at it, let's also discuss
what we wish to avoid.

Charlie and I look for companies that have a) a business we understand; b) favorable long-term
economics; c) able and trustworthy management; and d) a sensible price tag...

Our criterion of 'enduring' causes us to rule out companies in industries prone to rapid and
continuous change. "
