I think a postal shipping option (priority package) could only be beneficial for Shapeways. In fact, I'm quite sure the unique available shipping option is refraining a lot of people from ordering on your website.If you offer two shipping options, the buyer can choose which option is less likely to him to create a surprise fee. I have been hit by an UPS well-known "surprise" (+50 CHF on a $37 USD Shapeways order), I contacted the support and unfortunately the Shapeways team cannot do a lot to avoid this. I have to deal myself with local UPS, and this is not a pleasure. Because of the problematic shipping company Shapeways unfortunately isn't an option for me anymore, at least for little orders. This kind of surprise never happens with postal shipping. I would prefer to wait longer for my order to arrive, but be sure that I will not be hit by a big extra !
