About 15 years ago I was shopping at Total Wine (wine chain in USA) and the salesman recommended I buy a case each of the Merlot and Chardonnay from Canyon Oaks. By the case it was $2.50/bottle. He said they had dramatically overproduced the year before and dumped a huge amount on the market -- he thought the wine was very good for a $10 bottle (based upon prices then) and at $2.50 it was a steal.
Total Wine didn't have it available for tasting, but I had dealt with this guy before and had found his recommendations to be spot on. So I took the chance and purchase a case of each.
Two days later I went back and purchased another case of each. Wow! That was a great deal! I haven't found one that good since then.
Price is a funny thing -- we want to pay less, but sometimes we don't trust it if the price is too low. A restaurant owner I knew had Fetzer Sundial Chardonnay on his list for $7.50 (this was many moons ago). He told me that his normal process was to double the wholesale price, but the wholesale on this wine was $2.25. If he put it on the menu at $4.50, he wouldn't sell few bottles as folks would think it was junk wine. So he basically tripled the wholesale prices and it was his best seller in that price range.
