XYZ of the month Club: Whatever your product is, create a special one each month. You’re already familiar with those BMG or Columbia House CDs of the Month, right? (from back-in-the-day)… Well, you can do that with almost anything. Here are some examples:
This works well with consumables, ongoing hobbies, collectibles, etc. If it’s something people use/collect/do on a regular basis, give them something exciting to look forward to each month. Also, you can make them season-related at specific times of the year. Customers can buy them for themselves or give them as a gift.
