I have preordered some Tim Holtz Stamping Platforms and I have two left. The shipment is scheduled to arrive in mid April. If you want me to put you down for one of the ones coming in April email me at firstname.lastname@example.org. The cost is $32.25 plus shipping (just the actual shipping cost). I can get more later on but the first shipment coming in April is sold out with my supplier.
Here is another video that shows how the Stamp Platform works. It is not as entertaining as his CHA video but it is much more informative.
