Amazing tip from demonstrator Cheri S:
"My customers bring their catalog to every event. Once they have 6 signatures (I sign at every one they attend) they get a Snail refill. They nearly all use Snail now. I have done this for years. Also reminds them to bring their own catalogs that they have marked."
I love this idea! Many of us should not be lugging around a ton of heavy catalogs to events. And it's always better for them to have their wishlist and Post-it-Note covered-catalogs right there for ordering.
I would suggest putting a large custom-printed sticker right on the front or back of the catalogs to explain the policy and provide a visual reminder to bring the catalog and collect signatures.
