E-bay and pay pal allow uninformed buyers to pay without being invoiced or billed for a product they can not possibly pick up or take possession of thus causing days and days of hassle. The pay pal foreign representatives do not always have the language skills to deal with hearing impaired people. Included in my torture was a foreign rep. That could not deal with an apple computer running safari. When told to respond by e-mail they just ignore me. I have had more satisfactory dealings than bad ones.
