Final answer:
A 75-cent-off coupon for Gillette Foamy shaving cream in a package of Gillette Sensor razor blades is an example of a cross-ruff coupon. The correct option is A.
Step-by-step explanation:
A package of Gillette Sensor razor blades contains a 75-cent-off coupon for Gillette Foamy shaving cream. This is an example of a cross-ruff coupon. Cross-ruff coupons are promotional tools used to encourage the purchase of related products by offering a discount on one product when you buy another. For instance, in this case, buyers of Gillette Sensor razor blades receive a discount on Gillette Foamy shaving cream, which is a complementary product often used together with razor blades.
Speaking of shaving cream, there are different types which cater to various preferences and skin types. These include aerosol shaving cream, commonly known as shaving foam; latherless shaving cream, also known as brushless shaving cream or non-aerosol shaving cream; and lather shaving cream, which can either refer to cream that forms a lather easily, often used with a shaving brush, or to the lather itself that is produced from shaving soap.
The promotion mentioned aligns with the practice of cross-promotion, where two products that complement each other are marketed together to enhance sales and provide added value to consumers. The Gillette brand offering a coupon for its shaving cream with the purchase of its razor blades is a strategic way to increase brand loyalty and encourage consumers to try more of its products.
