Be careful what and who you order such things from. There are fishing companies out there set up solely to catch people placing scrupulous orders. They typically put watched, or drug making chemicals in clear sight or offer unrealistic prices on things(too low or way too high).
It is however typical when ordering a small order(anything anyone on here could likely afford) that it takes a month to 6 months to receive. Chemical companies are not interested in your 100 euros, they tend to have people ordering tens of thousands of euros of stuff from them frequently. In fact, they may never(waiting at least a year) fill your order because of it's low priority depending on how big the company is.
Yes lists really do exist of who orders what and when and where to. Use discretion. A sketchy order can lead to a door being kicked down, or an investigation, even if the package is not received. Even if you receive a package that does not mean 6-12 months to 5 years later you won't be visited about it.
Company may say its in Netherlands but might actually be in the US, or EU. Always a good idea to do a background check on these types of companies.
I find it bizarre that when you try to visit the web-site using TOR(anonymous surfing) the whole page is spammed with symbols so you cannot read it. Probably not a good sign...
Now I don't know much about ordering chemicals having never really done it outside of a professional environment. I do know that many companies will not sell chemicals to non-business owners.
Also if a company sends you something that you ordered, if its shipping violates haz-mat or similar institutions rules for such the purchaser is responsible.
I should probably talk to Trav about adding this sort of discussion to the rules. As it can draw a lot of unwanted attention to a place.
