Ouch, that sounds like a real nightmare.
At that point I would just refund the item back to seller unless its not sold on your country and has to be imported.
That particular point is not the worst. Trust me. Even after me paying these taxes I find that product comparatively cheaper than what I get in my country. For example, if I buy something from outside my country for 1000$,pay 200$ for tax, it'd amount to 1200$,and for the same product in my country I'd have to pay like 2000$ without adding VAT.
I know some sellers that can under-value an item, basically he will write lower price on invoice than the actual price.
With this sometimes you don't have to pay enormous tax at all.
Exactly, but this case happens very rarely so good luck with anybody waiving their taxes off.
