As a small seller it is unnerving, and very risky to use
ebay low start price auctions, because if you don't have that "interest", you can end up with nothing or next to nothing (yes, I've had that happen too many times). I just quit trying. The "big name sellers" seem to have the following and everything catches enough interest, some even to the point of a frenzy resulting in better than expected prices.
As a buyer, I've tried putting in my highest bid up front, and that NEVER works on
ebay or hip. For some reason people just poke and poke there way up so they're "on top", which just results in the price going even higher.
I'm finding winning anything worth having VERY difficult these days as well. The "price point" seems to have gone up VERY significantly from 3-4 years ago, but I still don't know what that price point is. There seem to be a few very deep pocket, aggressive buyers for the better, more expensive material. Just the other day an item had a bid of about $20 ten minutes before auction end. I had a snipe bid at about 30% of catalog which was 15 times the current bid, but was still outbid - only one other bidder bid more than $30! I'm seeing people bid 3-4x higher today for same items I'd buy for 1x 4 years ago!
This is good on one hand - I don't spend as much which pleases my wife, on the other hand it leaves me quite frustrated since what I'm after is more limited and specialized than ever and I never win anything! :-)
