Those that weren't fortunate enough to snag Amazon's limited trial of $7.99 per-month Prime subscriptions are now officially out of luck. Representatives have confirmed to AllThingsD that the company is no longer offering the monthly rate to new subscribers. Last month, it was discovered that the company had begun offering its premium streaming video and membership service, Amazon Prime, for a fixed monthly rate — a notable departure from its long-standing annual fee of $79. The pricing structure was believed to be a direct response to Hulu Plus and Netflix, who offer similarly priced monthly plans. Amazon says it has concluded the trial but has offered no further comment with regards to when, or if, it'll offer it as a standard option in the future.
