The vendor has 12 positive and 0 negative feedback, and he has escrow enabled, but only 6€ for a 115ug blotter looks suspicious. The blotter art looks like this:

Personally, I have never seen anyone selling LSD for less than 1€/10ug, except in very large offers (where we talk about hundreds or thousands of blotters). Is this offer legitimate?
Why should you pick a 12-positive-feedback vendor when there are many hundreds-positive feedback vendors? I believe their positive feedback tell quite much about their quality and services
