There's a lot of great ideas in this thread!
I'm re-opening my etsy shop soon and needed a refresher to get back into the swing of things.
I'm a big fan of doing blog give-aways, I like to include little freebies (like keychains and such with my shop address/name on them) and definitely business cards as well as Thank You postcards that occasionally include specials like free shipping etc.
I've found that word of mouth has been my biggest help towards sales. I tell everyone what I do when I get the chance, and even leave business cards behind at restaurants if I get a waiter/waitress that I think will dig my stuff.
I have yet to make a Facebook Fan page thought I'm thinking about it. Anyone who's done it, how do you like it? Do you think it helps?
