Ordering and payment

How do I place an order? Are lenses included in the price? How much do glasses cost? How does the 2 for 1 offer work? Can I use a discount code with the 2 for 1 offer? Which payment methods do you accept? My Klarna invoice is due soon and I haven't received my order yet. What should I do? Can I order in my company's name? Can I get an invoice with a business ID? Can I get my glasses reimbursed?
