Just got this email from Shapeways

An End of Year Thank You Gift!
We would like to thank you for all your support that helped make 2011 an amazing year at Shapeways.
To thank you for your continued support, we are slashing the price of our most popular material, White Strong & Flexible by 20.11% until the end of the year.

Every model ordered in White Strong & Flexible will automatically be 20.11% cheaper for material cost (the designer's mark-up will not be discounted).
So if you order a little something for yourself it will be 20.11% cheaper, if you order a big something for yourself it will be 20.11% cheaper.
You got it, WSF, 20.11% cheaper until midnight, December 31st 2011 EST

If you've been thinking about getting a new puzzle soon, looks like now would be a good time

I wanted to use this offer, but I found never the 20.11% discount expressed explicitly during the order process.
I was ordering TomZ's 4x5x6 and the calculation did not fit with a 20.11% discount off the originally announced price of USD 185.

Neither can I. I would really like to buy David's Fractured-6 puzzle with the discount, but I'm not sure where the discount is applied.

The discount is applied already to the listed price of WSF on shapeways. FOr example, TomZ's 3x4x5 is normally $149, but it now says it is only $135. The discount is taken off before the designer's markup is added, so it won't be a full 20.11% off of the original price, just off of the base price of the puzzle.

I'm sure that you will not see the full 20% discount due to my markup, and EUR/USD and VAT issues. However, I checked and the prices are lowered when ordering in WSF (BSF, WSFP do not get the discount).

I'd like to remind you that the Multidodecahedron is still available. Please send me your order number via email or PM if you order it, otherwise you will not get your puzzle correctly. Free stickers (shipping time directly from me can vary!) are included.

Thanks Tom!
It is not very clever marketing anyway.
People would like to see the original price and the discount they get explicitly.
So, something like the 15% discount off with a coupon code makes more sense to me.
Because I want your 4x5x6 in black anyway and I have never dyed WSF before, I will wait for another opportunity.

Somehow on topic, because people may want to order your glorious Multi-D:
Regarding my Multi-D stickers: I have got them today Finally!
They are great. Perfect size (for my taste at least) and they stick well.
Very well cut by your laser cutter, too. I had never the nasty problem where I could not remove the stickers from the scrap (E.g. the Classical Tuttminx had this problem recently, but I had much worse.)
I got them this afternoon and have stickered the Master Pentultimate parts, so far.

EDIT:
I deleted the address comment. I did not want to sound critical and I should have better written a PM. Sorry Tom.
I have completed the stickering yesterday evening. Great puzzle and great stickers.
If Shapeways would give a discount for the polished WSF, I would consider to buy a second.

Brad of Shapeways just contacted me to clarify things a bit:
It seems they can only create coupons that work towards your entire order and not a specific material, so they simply changed the pricing of WSF to reflect the 20% discount.
