When is wine a good value?

It seems you can buy wine almost anywhere these days. That can make it tough sometimes on your friendly, local independent wine retailer.
Sam's, Costco, Trader Joe's, Walgreens, Amazaon.com, even Aldi's is hawking wine at dirt cheap prices. 
I generally consider wine to be a good value if it is under $20 retail and of high quality. The high quality part is essential. At Balabans, I spend more time trying to find high quality value wines than anything else. A quick physical count shows we have over 100 labels under $20, with many wines at $9 and $10. And I can guarantee you every one of those 100+ wines is of high quality. Because somebody here tried them before they were purchased.
Cheers to value!
