Simplify with a Spreadsheet

Using a spreadsheet will be beneficial when determining the cost of different quantities of oils (drop, 2 dram, 5ml, 15ml...etc.)  Once you input the proper formulas for one oil,  you can then copy the formulas for the rest of you oils and just enter the different purchase price of each oil.  This is a great way to breakdown the cost of any ingredients you may purchase in bulk.  Takes a little time in the beginning, but saves you so much down the road.
