How to buy

• What purchase and payment options are there?
• My university/company/institution can only do a purchase on account (payment after completion / payment upon receiving). Is that possible?
• Where is my order?
• What are batches?
• What's the size and weight of your shippings?
• Are there any hidden costs? What about customs and taxes?
• Where can I buy a THAT?
• How can I get a quotation?
• How can I get an invoice?
• What about the patch cables?
