It's not clear to me whether the quoted prices include shipping. Presumably not, as they don't ask for my location.

I was ordering 3D printed parts just a few days ago and finding shipping costs was a major frustration: every site would quote $5 for 5 copies, send me to make an account, and only then tell me the price was $5 for printing and $50 for shipping.

Obviously I could have ordered more copies of my part to make the order more efficient - but we all know the first print of a snap-fit part isn't going to fit properly, so these prototypes are going to end up in the trash anyway.

So that's my feature request for you: Shipping prices upfront, not gated behind creating an account.
