The profit margin provided by sales of hand stamps or self-inking stamps should cause any awards and engraving retailer to consider the addition of the product. Regardless of the method used to make the stamp, the material cost of a hand stamp is seldom more than $1. The retail price for a three-line name and address stamp ranges from $8 to $12 depending on the local market. Self-inking stamps cost $5 to $7 in materials and retail from $16 to $25. Offering wholesale stamp services with a 35 or 40% discount to area printers and office supply dealers can quickly increase the volume of stamps sold. While the margin per stamp sold is smaller, overall profitability will be higher.
