Sometimes you just have to take a leap in the dark.
I mean, there is hardly anything out there about Gokudo-kun Manyuki so when my sister's boyfriend bought it, he really had no idea (not like he knows anything about anime, anyway).
First of all I'm able to spend a lot of time just in an anime store, comparing movie (or series) to movie and seeing which one would be a better investment. I tend to buy more movies because they're cheaper to collect right now - it's silly to start buying a series when you know it'll be ages before you can buy the next part.
And really... most people who work in the store have already watched the things they're selling, or have an idea about it. If they're any good they'll give you very good info about it, so you don't really need to do all the researching and all.
Personally I mostly trust my friends - if they say a certain anime is worthwhile, I'll be more interested in buying it.
