Rules for Importing Data via .csv

The rules for importing are simple:

Make sure your file type is a .csv file (not .txt, .xlsx, etc.)
MSKU, Cost/Unit, and Purchased Date are a must have. If you leave the other columns blank, that is okay - headers need to stay though.
Prices cannot have a $ in them
Dates must be in MM/DD/YY or MM/DD/YYYY format
Headings should not have any commas. As a comma-separated import, it will separate incorrectly.
