Try to include as much detail as possible in the title. Then expand on it in your post. General info to provide: expiration date of the coupon, minimum purchase requirements, site link, shipping and handling costs, and the coupon code. The more information you include, the better. Follow up if possible, so you can edit your post to include new developments. Be careful when using dashes in your post, they can make it seem like you are getting paid in the deal. (ie, .... chair -$59)
