We currently only accept bank transfer — full details are provided upon checkout.
Why don't we accept card payments? Unfortunately despite progress, the industry is still heavily stigmatised (from banks) which means that even payment gateways such as PayPal don't provide a service for any spore provider based in the UK (also the reason that you cannot buy these spores on the high street).
Is this your first order? We encourage you to read our customer reviews to see the experiences others have had with us.
What happens after I pay? Once we have received payment, a confirmation will be emailed to you. Please allow a few hours for this (within office hours). Meanwhile we'll start preparing your order.
