Fixes to 2 websites - Wordpress/Woo commerce

I need some issues fixed for my websites [login to view URL] and [login to view URL] I need a couple of issues solved with payment and shipping options (using Klarna as payment gateway, they have english support) - only on [login to view URL] - shipping of my salt products should be more expensive than rest of products because they are heavy - I now have the same store credentials on both stores, even though I have three separate accounts with Klarna. I need this to be corrected, plus the third account in Klarna to be used on a specific webpage ([login to view URL]) for purchases of recurring payments for a subscription service of scents. - only on [login to view URL] - on orders that have free shipping we give the option of collecting the goods or get them sent to a courier shop near the costumer. but the costumer never gets to choose which one so we have to contact each costumer manually. - all shipping should be without VAT, right now VAT is added Also discount codes need to be one-time-use only, now the same code can be used over and over by the same costumer only on [login to view URL] last on the main page is a frame collecting email addresses, but once the email has been collected, an email needs to get sent out with the discount code promised For both pages discount codes needs to be valid only once per user the page [login to view URL] need to have a form with fields to fill in like name, address etc plus a choice of all scents sold on the site, so that the costumer can choose their favourite scents any number they want and once everything is filled out, hit a "send"-button and all that they filled in should be collected in a database plus sent out in an email to us Links to shopping cart from bottom ("Min kundkorg"), & go to checkout (Gå till utcheckning") and My account ("Mitt konto") doesn't work, all located on the bottom of chocolate landing page
