Read the following context and answer the question.
Context: But this is the one wine where I splurged for a whole case ( at $ 13 a bottle ) , which is now , sadly , running low , thanks to my own depletion - and giving one to my aunt . In all honesty , this wine is listed at $ 16 retail so a tad above her threshold . But with a 10 % case discount , she 'll be in the clear .
Question: Why are there limited amounts of wine left ?
Answer:


I was gradually drinking the wine myself over time .
