We're now receiving orders from all over the country due to our Web Site. It's important to make sure that you include your site URL on every piece of marketing material you hand out - stationery, business cards, flyers, etc. I recently purchased a series of ads in bridal magazines and made sure that each ad included our 800 number and the Web Site address. We're getting more and more online visits and orders every day. Our site is not on a secure server, so we made sure that people can print out a fax order form from the site on their printer that they can complete and fax to us.
People feel comfortable about doing that, especially with credit card orders.
Don't be afraid to be different in your marketing. Mail them to your clients a week before the show to remind them that you're going to be there. Marketing with chocolate can lead to sweet success.
