Tip 1 - The entry
When you walk into the store and the pretty young cashier says "can I help for find something", your answer should always be "no, thank you". Her help, while potentially entertaining, will not help you find the records you're looking for.
Tip 2 - Pricing it out
If you're in a major metro area, and they're priced at more than $2 each (and even that's high here in Philly), leave. If you're just looking for some new records to try out or add to your collection, $2 is it.
Tips 3 - Feeling it out
You see the sign; "All records, $.25" and see a large selection, now it's time to get to work. Big and Heavy should be your mantra. 78's almost always come in albums (at least the singles are long destroyed or are on Ebay), unfortunately so do a lot of 33's. 78's however are usually at least twice the weight, the albums are longer (depth wise, to support the binding) and come in packaging colors so austere that they were likely developed by (a) the same people who recently got laid off from packaging WWII cans of rations, ammunition, etc... or (b) the guy in the USSR who was just too "radical" in his use of color.
Tip 4 - Quality Control
Once you've found your large, brick-like Soviet style album, you probably know before opening it that they're 78's. But just to be sure, open the album and look for "LP", "Stereo", "33-1/3RPM (of course)" or "micro groove". Or for that matter, pictures, colors and clever advertising. If you see any of the above, it's probably not a 78. Also look for cracks, broken records (look at each one) and missing ones.
Tip 5 - It's Like gold mining
There's at least one in that pile, and your hard work will pay off, someday (assuming you like Classical or children's music).
And I'll leave you with this question... why can't I ever find any swing, foxtrot, jazz, or anything other than classical or children's music???
PS. Most of the above is meant to be light hearted and humorous and not necessarily practical
