Is there a Virtuix Omni system "package" or "bundle" available for consumer purchase in USA?
The Title pretty much sums up my question;
Is there a way someone can purchase this product: the stand, the mat, the base, the harness, etc.
within the United States?
As a private consumer - you can't buy one from Virtuix directly. You might be able to find a reseller, though.
If, however, you are the owner of an arcade or some other commercial establishment, you can request a quote from this page:
