This is not Ebay in the traditional sense. What this is, is their Daily Deals section of the site. This is reputable merchants who are selling through Ebay in a one-day promotion. For example, the Xbox Live card is being sold by Tiger Direct. Anyway, the iPad and cell phone are sold out, but the rest was in stock at the time of this post!
You can score these deals and other amazing deals every day by joining Ebay Daily Deals <----- here!
