So far our sample size of 11 does quite clearly favour larger sizes (1kg). But, as you all say, it does depend on what you are buying. People do appear to like the idea of being able to buy samples. The other thing mentioned was that you thought our filament prices were too high. so in response to these points:

1. We are going to sell filament samples from the website. this should be available this week, in limited colours initially.
2. We have dropped our prices in-line with expectations so that you can get both ABS and Ingeo PLA fro £18.35 Kg
