Donna, they ship the bars in ice if it is too hot. The bars, which are larger than a normal bar at the grocery store, are roughly $2-$3.50 wholesale. If people really love chocolate, I mean real chocolate; you won’t have a hard time selling it. My most expensive bar, $7.95 sells more than the $3.95. This proves my point of "trading up" that I am always preaching about. Trading up in a nut shell means, people who are passionate about a certain thing, golf, cars, chocolates, flowers, don’t mind spending more on these items. Most of these people are middle class, clip coupons, shop at Wally World, but don't mind paying $8 for a bar of chocolate that is like no other. (Trading Up)
On a side note, I paid too much for a Domorri chocolate bar, Italian chocolate, and it was like nothing I had taste before. It was amazing. It was also $13 a bar, which is too much, but it was saved for my anniversary.
One other thing I suggest you carry is truffles. Joseph Schmidt, the creator of the American truffle is out of SF and are fun and pretty decent. They have these pumpkin truffles that go off our shelves fast in Oct/Nov.
Some things to know... your chocolate should have a long shelf life, it doesn't need special cases really, Fall/Winter you sell a lot of chocolate and a cute display always helps. Some marketing ideas is if you use the chocolate in that top 10, let your customers know about it in shop and in your ads. Below is a image of an ad I did that will be going out in a local publication. Let the people know you carry the finest chocolate in your area. Call me on my cell if you have questions, I can, if I am in front of my computer, hook you up with some distributors. I'd love to help!!!!
