What if my order does not arrive?

In the rare event that your order does not arrive, we have two options:

  1. All Customers who selected our Insured Tracked Postage Service will have their full order reshipped if it has not arrived.
  2. All other Postal Services are non-eligible for our reshipping service.

What payment methods do you accept?

We accept Bank Transfers and various Crypto Currencies including Bitcoin, Bitcoin Cash, Litecoin, Ethereum and Monero.

Where can I find your bitcoin address to make a payment to?

When you use Cointopay, they generate a unique Bitcoin address for every single order. So, never try to send funds to the same address as a previous order.

If you’re unable to find the unique BTC address during the checkout phase, there’s a good possibility that you have an Ad/Script Blocker enabled on your Web Browser.  We ask all Customers to either disable their Ad/Script Blocker or add our website (https://chemtheory.com) to your white-list exceptions.

Popular Ad Blockers such as uBlock and Adblock will prevent your unique BTC address from being generated. This also applies to Tor Browser. Tor Browser has in-built Ad/Script blockers that cannot be disabled, preventing you from successfully paying for your order.

Why it is my BTC payment is higher than that stated on the likes of Coinbase or Preev?

Cryptocurrencies come with various network fees that are not taken into account on exchange services like Coinbase or Preev. Our fees include the network fee, in addition to the fee charged by our chosen Payment Provider. If the stated amount is not paid in full, your funds will be held for 7 days before being refunded with a 10EUR deduction penalty for time wasting.

Do you offer free samples?

We do not supply free samples. However, if you become known to us here at Chem Theory, as a regular Customer, and you’re interested in a sample of one of our products, you can either email us directly at [email protected] or request it in the comments section when placing your order.
