I've bought several now in the past. I've paid with PP and with my CC on separate orders previously. My CC charged me the same (ish) as if I'd used paypal, so there was no real difference, at least for me.
The question I asked here was more about what it's declared as? I looked through the list of codes for imports, and there's a few different categories that this product could be classed as, some are 4% duty, others are 0% duty.
What was yours marked as, and did you buy it in January, as its the purchase date that matters, not when it was shipped.
I've ordered anyway. It was £150.04 via PP this time. Last time it was £180 with PP and that included 21% Czech Republic VAT.
So much for a "trade deal" when everything still gets slapped with import duty.
