UPDATE
I just received a response from Shapr3D regarding my enquiry. It now makes sense:
Here’s some clarification regarding the pricing and subscription options:
** App Store Pricing: The App Store subscription includes VAT in the displayed price.*
** Website Pricing: VAT will be calculated and applied during checkout if you subscribe via our website. VAT depends on your region.*
Both subscription methods offer the same technical features and access. The primary difference lies in how payments are managed:
** App Store Subscriptions: Apple manages billing, cancellations, and refunds.*
** Website Subscriptions: These are handled directly by our support team.*
