I ended using my own card, and although this question was approved, S3D apparently has no answer to the question. I am enjoying the software.
The 'contact us page' is broken as far as my macbook is concerned so I am posting here.
The resellers I found bundle with hardware, and we already have hardware. My employer uses Amex, Simplify 3D does not.
Any ideas? Thank You!
Best,
Shaun
