Daily for me. Sometimes I wouldn't buy enough and have to go back out. I don't know how I thought I was able to fool the clerks. I was trashed.
At the end, I gave up rotating liquor stores and just went to the same one every morning. It took only 3 days before I bought out all of "my" wine. Then, I moved on to my "2nd choice" and so on. At one point I had to go to a different store because I bought all the white wine. I was so happy when they would re-stock.
