Believe it or not guys make great customers. They are usually clueless to what to buy their partners so if you offer them suggestions and ideas or even put a pack together for them they will love you for it.
Granted they won't be regular customers but around gift giving time (like Christmas!) it's worth giving them a brochure.
Also gay men make excellent customers. They are usually excellent at looking after their skin and will like the skin care and personal care items.
Good luck with your Christmas selling!
