How do I place an order?  How do I change the address?  How do I change my email address?  How to get an invoice?  Why is my order marked as unpaid?  Why was I charged twice?  Can I modify or cancel my order?  Why was my order cancelled?  Can I make a VAT free purchase? Customer Support hasn’t responded – what now? Can I order multiple parts from different sellers? How do I know if my order went through? Can I reserve a part before purchasing? Can I order parts to a different country than my billing address? I placed an order but didn’t receive a confirmation email — what should I do? I accidentally ordered the wrong item — what can I do? Can I see reviews or ratings for sellers? Can I rate or review a seller after purchase? What should I do if I entered the wrong phone number at checkout? Why was my payment declined? What happens if the seller doesn’t confirm my order when I place it? Can I combine multiple orders into one shipment? How do I finalize my payment? Where is my order right now? Is my order confirmed?
