During the latest podcast, there were questions about which material was the most popular, and in particular what was the popularity of the Full Color Sandstone material. Obviously this depends on what you offer in your shop. Here is for my shop the material the most popular. I took the Excel file, removed the cancelled orders and classified the materials in function of number of items sold and in function of markup: As you can see, White Strong and Flexible is by far the most poplar material. Full Color Sandstone arrives second, and then White Strong and Flexible polished 3rd, which is not bad for a very recent material (I sold my first model in Sept 2009). You can also see that FD is not present and FUD is very low (those materials were introduced only 2 month ago), so the change in the pricing scheme won't affect my shop so much. I don't know if you have similar results, but if you want to share I guess it will be appreciated .
