They've go it all figured out for you.
"This is an ever-expanding metaphysical market, thanks to cassette recordings and CD’s. Most everyone owns a cassette recorder or CD player today or can purchase one inexpensively. The average cassette tape in metaphysics today retails for $9.95. We will round out that figure to $10.00, as we are taking an average. Cassette duplicating companies vary considerably in their prices, but the average duplication cost for a cassette tape is about $2.00, when ordered in small quantities. That leaves a profit of $8.00 per tape, less the cost of advertising or promotion and mailing costs if sales are by mail order. You can figure that about half of your profit or $4.00 will go towards this, leaving you with $4.00 as an average profit per tape. If you sell through stores, you would generally give them 40% of the retail price. However, because of a larger volume through store sales, your cost of reproduction would drop to approximately $1.00 leaving you with a profit of $5.00 per tape. If you were to sell 100 tapes per week, you could expect to earn a weekly profit of about $500.00. Not much, agreed, but if you were to put out a series of tapes (let us say five), and all were selling 100 copies per week, that could net you a total of $2,500.00 each week. Again, our universities cannot guarantee this will happen, but it has been done by others. In recent years, CD sales have overtaken cassette tape sales. That is a very good thing because the profit margin is much higher. The average CD in the holistic metaphysical field today retails for about $16.00. Cost in fully packaged CD’s from duplicators generally run about $3.00 in small quantities. That leaves a $13.00 margin between cost and retail. Figure $3.00
per CD towards promotion leaves you with a $9.00 profit per CD. If you were to sell 100 CD’s per week, that would equal $900.00 per week. If you were to sell to stores, less 40% or $6.40for their profit, you would be left with $8.60, less your cost of $3.00 leaves $5.60. If you had recorded 5 CD’s and they all sold 100 copies per week your profit would be $2,800 per week. No guarantee can be made as to how much you would earn—but the profit potential can be enormous. DVD’s and Videos can be produced in relatively small quantities including packaging from $3.00 to $5.00. The average DVD or Video in the Holistic New Thought Metaphysical field retails for $19.95 or $20.00 rounded. That leaves a margin of $15.00 to $18.00 if you are selling by yourself. Figure about $3.00 promotional cost per unit leaves you with $12.00 to $15.00 net per unit. Sales of only 50 weekly could net $600.00 to $900.00 weekly. Sales to stores offered at 40% off wholesale on $8.00 would still leave you with $7.00 to $9.00 each profit. The potential earnings from having just a few titles out in stores can be outstanding."
