Well considering that Express shipping will cost roughly $30, the heatpack and packaging another $5 or so. That leaves you around $15-18ea for a high grade CRS... I don't think that's unreasonable if you're looking for high grade shrimp. Considering how fragile these are and the fact they're not a beginner's shrimp, I'd say this isn't a rip off at all.
I've purchased CRS from kangshiang a couple of times and was happy with each package.
Not trying to argue BJRuttenberg, just offering a differing opinion.
They are awesome looking specimens. I hope you will be selling more in the future. I need to find out what they need to survive as I have never kept shrimp of any kind. The price isn't that unreasonable as I've seen CRS go for more than this that didnt look as good.
