Great way to track what products need to be shipped to a customer on a regular schedule! Set your customers up for "auto ship" on items that need to be replaced on a monthly, bi-monthly or tri-monthly basis. For example: mascara needs to be replaced every three months, and say she needs 3-in-1 Cleanser every two months. Fill out the Auto Ship Worksheet and file it under the day of the month to be shipped. When you get to that date, the Auto Ship Worksheet reminds you what to mail. Payment information is right on the card, so charging her credit card is a snap. What a great way to serve your customers and create income! (25/pack)
