MediaMegaMall is primarily devoted to selling at the professional, large quantity level. Their deals are tailored to appeal to those buyers. They have offered free shipping on 2 spindle purchases before, but I haven't seen that for a while now. If you happen to use Blu-ray cases, putting together an order of 100 of their double Blu-ray cases and a couple spindles of discs gives me a very reasonable $12.50 shipping and a good deal all-around.
We are all frustrated by the fact that most brands selling BD-R's are switching to different sources and media codes and making buying them a game of Russian roulette :a. This is why a find like SmartBlu is such a breath of fresh air in the lower cost BD-R range.
The only other low cost option I would consider right now is Melody BD-Rs. They have been yielding good burn quality at 4-6x burn speeds in my burners. Not quite as much overspeed headroom as the SmartBlus.
