I wouldn't go around looking for superbargains on the internet, they don't exist.
The market has a lot more buyers than sellers, ebay is not a place where you usually put one over on a seller and the buying population.
Well, I've been burned on eBay a few times; and one of those times was from a MAJOR player with literally tens of thousands of past transactions -- and that was the *one* time I filed a dispute. The dispute was settled in my favor in a matter of hours: I got my money back AND was allowed to keep the pens; but I was NOT allowed to then give feedback (which makes me wonder how many OTHER people were like me and got screwed by the seller). But overall I have had good pen-shopping experiences on eBay, and there are several vendors who have gotten orders from me on more than one occasion (and if the Japanese seller where I got my grey Decimo from last year has what I'm looking for at a good price I would not hesitate to be a repeat customer as well).
Oddly, the *only* times I had bad experiences on eBay were in buying pens -- I've done okay for other purchases.
And while I haven't bought pens from (or through) Amazon, most of my other experiences (music, DVDs and books for the most part, although that was also the cheapest place to get replacement cartridges for the laser printer) have been pretty good as well. Although I sweat buckets about a CD I ordered from a third party seller in, IIRC, Austria -- because the seller did not allow returns, and I was worried that the CD would be damaged, or in some format I couldn't play (the way DVDs have different formats depending on the country); and it was not readily available otherwise -- it was something I never even found on vinyl, back in the day, and ONLY had as a cassette tape (found in a bargain bin in a store in a downtown urban mall in Bridgeport CT in the late 1970s....

ETA: Nearly all of my pen shopping on eBay has been for vintage pens, not modern ones; and the modern ones have MOSTLY been from reputable sellers.
