The dictionary definition for investment goes something along these lines: 'the investing of money or capital in order to gain profitable returns, as interest, income, or appreciation in value.' Taken from dictionary.com. If you are one of those people (not vendors) who purchased oudh and then resold it , for whatever reason, did you make profit or not. Please answer based on actual sale of an oil, not what you perceive to make IF you sold it. Your answer should also be based on the retail value of a particular oil at the time of your purchase and not a discounted value. Sometimes vendors give a discount to clients and there is an immediate incentive there to make sales, however I am more interested in true gained value. Where you purchase the oil which is retailing on vendors site for $1000 and you pay $1000 then few years down the track you sold it for profit greater than inflation. Assume inflation at 3% per year.
