Yeah, absolutely. I don't ever want to get that that 30,000 records "I bought this album for one 30 second sample" guy because I'm not a fucking DJ or anything, I'd just like to have a solid collection. I've definitely purchased a few questionable records just because I had money to burn on something dumb. I have a buddy who will buy 5 copies of the same album to have every colour variant of the pressing, it's fun to look through but it's a little excessive. I have a habit of being a completest when it comes to music, so my lists usually just pertain to everything I can find from a particular artist. I know it isn't vinyl, but with everyone wanting to collect stuff on wax people are dumping their CD collections. I've found a bunch of great stuff real cheap at Value Village and other thrift stores. They're so picked over for vinyl more often than not I won't even bother looking.
In regards to being the Discogs guy in the store I could never do that, equating it to a skateshop is a great example. I'd never stand in a shop and price check everything.
