Similar to popular auction sites, when you submit the Purchase This Item form, you are entering into an agreement with the seller that you will submit payment to them in exchange for their shipping the product you have purchased. Your information is sent to the seller, whose obligation it is to contact you to negotiate the exact method and amount of payment. The transaction is completed privately between you and the seller.

Some products in the catalog link to external web pages, where further information on the product and how to purchase it may be found. These products are not represented by a particular speaker, so you will see a link at the bottom of the product page instead of the usual form.
