Part of me wants to ask if you're trolling. I paid over 100€ for 100 grams and some here have paid even more. SN is not supposed to be that expensive, just look up any site selling it for scientific purposes. It's out of reach because using it to CBA has been caught up to, so now it's only sold to those with appropriate licences to proof what they'll be using it for, even if buying or owning the substance would be perfectly legal for private persons too. And anyone selling it without asking for such licences, does so at a huge markup because they know the desperation people like us have. In any case, I'm not sure what SN is "really" worth for, but what you paid is closer to the real market price of what it's supposed to cost, assuming it's legit.
