$8 shipping per order, regardless of size, within the USA and APO/FPO. Large items sent UPS ground.

For other locations, inquire. I don't like shipping to foreign countries because insurance is only available if you pay a bunch extra, and then the customs guys might sock it to you. I cannot be responsible for shipments that don't make it. Nor can I even prove I sent anything, so recognize that if you order from out of the country you might not receive anything or even know whether I sent anything.
That said, I have sent stuff overseas many times with no problems so far. Except things take weeks to get through Canadian customs. Even longer to Bolivia. And nothing gets to Nigeria.
If you are in Europe, I can recommend a friend in Romania. There are few crafters that I know of that I consider in my league, in terms of intensity per cc. Most other resin-based orgone devices on the market are wimpy in comparison, no matter how beautiful or complex-looking.

Payment methods: I accept PayPal, but they charge me ~4% on most donations, so I will give you a 5% discount if you pay by US Postal Service money orders (not just any old money orders) or cash (better insure it or be willing to take the risk if you send cash). If this is a problem, or if you are overseas, email me, and we might be able to work something out. Barters considered. Note: not all items are in stock at any time. Please let me know what you want, and I'll get back with you to arrange matters.

WISH LIST for Barter:
I might be interested in any cool minerals, especially large green aventurine, largish rough emeralds, black tourmaline, mica, rutilated quartz, smokey quartz, amethyst, spheres, Vogel-cut crystals, pyramids....
Possibly other items. Especially large xenon or other noble-gas ampoules, radiation meters, etc.
