Severe pricing issue with BD-R 50 GB

The 25GB ones are like $3.75 to $39.28 a disc, which, at the lower end, ain't bad. However, the cheapest 50GB writables are $20.99 a disc. I mean, that doesn't make sense. Veribatim has a 25GB for $6.30 and $6.49 a disc, but their 50GB is $20.99 a disc. Wouldn't common sense point out that the 50 GB shouldn't be more than $12. Does anyone know why consumers are getting ripped off like this?

And we wonder why Blu-Ray movies cost so much.
