Uwe just announced that for the 42nd birthday of the pyraminx, he's giving 30% off quite a few products from his store. It includes the professor pyraminx which is now only $30 instead of the usual $42. Check out all the discounted products here.
The prices show up as normal on the website but as soon as you add anything to your shopping cart you see the updated prices.

Thanks Tom, I finally got a Pyraminx Crystal and a Holey Skewb

I would add that some of those puzzles are old stock so the quantities of them are fairly limited right now. I don't know if he will remake them or move on to new puzzles.

Seems the link didn't work in my email that Mefferts sent for the following book:

The Amazing Pyraminx, by Dr. Ronald Turner-Smith

Does anyone have the link to this?

Thanks.

Me too - I'd like the link for this book as well.

Thanks for the link to the file! Everyone holding back on specific versions of the Pyraminx may consider the new sale enough of a difference for their budget.

Thank you katsmom!
