Sega has a weekly contest in which they give away various pieces of Sega merchandise throughout the day. They've been doing this for a couple of weeks, but this week has their first Phantasy Star prize. Sometime today, they'll be giving away one of the inflatable Phantasy Star Ø rappy armbands from last year's Tokyo Game Show.
Details on the contest and how to enter are available at Sega of America's blog. Some prizes are region or age restricted, but the rappy is available to everyone.
