So you type the five letters (after discovering that the flat text is a "button"), click the Apply Discount button (flatish but at least it got a frame)... and nothing happens. What other conditions are required for this? Only for USA people? Only if paying in dollars? What?
Edit: wild guess: taxes and shipping not included in the limit. If using the free shipping code, it works, and the shipping ends being just 0.01. Yes, there is a rounding issue somewhere, shipping cost is one number, the coupon reports a similar number in negative, but not exact.
Wait, once you reach 75 dollars, then the discount applies... and to taxes too? So that makes it work after 90.75 dollars or 75, it depends. Errmm... Shapeways should stop prettending it accepts euros at the same level than dollars, it's confusing. You could just say it isn't working and never will fully do without some radical changes. And there are are silly cases like asking for euros when the address is in Norway (not using euros, not in EU, just some special deals here and there). Well, not asking, but forcing.
OK, rant over... it would just great to be able to control things and avoid currency exchange rates. It's not asking for double Irish Dutch sandwich, just a clean glass without soap aftertaste.
