beginner question: krogger or wine store?

[greenhorse]

I want to start trying wines and just bought a reisling from krogger for $10. I'd like to drink occationaly and try different varieties to find my preference. I want to try decent things but not too expensive. What price bracket is good? What kind of things I should avoid, like cheap bottles or wine from exotic places?

There is a wine shop In the same plaza. I wonder whether I should buy wine in a wine shop, maybe they have better wines? There are so many varieties and brands that I feel like a fool. Besides I'm afraid they are too expensive because there are no price tags in the wine shop.

Thanks.
