Our Customs Agents periodically look around eBay for pricing if they get suspicious about an item's worth when inspecting. I have never asked anyone to falsify the true value to a ridiculous amount. It has to be bona fide pricing.
Another thing I will not do is haggle the asking price with a seller. It is what it is....and if I don't like the price....I don't get involved. If the item is what I want, I'll pay what the guy is asking. I learnt that lesson a long time ago.
Something else that many do not consider.....because the shipping process can take up to 3 months from USA to down these parts....a Warranty can expire, and a PayPal transaction can expire as far as refunds go. I found that out when I purchased a Holley electric fuel pump a few years ago for my truck. The Holley pump was junk, but by the time it arrived, Summit Racing informed me that their 90-day Refund Policy had expired. So I was stuck with a $300+ piece of junk.
I am very wary of buying retail from Summit Racing now.
