While I go to eBay for items I can't find on Amazon, Amazon is my go to place because they will precalculate and precharge "import fees deposit", which covers both customs tax and VAT, and will not double charge VAT on me (I am in a non-EU European country). This also helps avoid "customs processing" fee some couriers charge locally (at 30€ for DHL or 40€ for FedEx, fast shipping smaller, cheaper items balloons quite quickly: UPS has at least stopped charging this lately).
