What is reflected on those sites I named is what reality is. Ppl go on there and wil lbid on ebay auctions based o nwhat they see prices at there. So yes, I meant what I said. Prices do fluctuate, but for the most part you can get a good read from those sites and go from there... If it goes down on those sites, what happens, you usually see it pop up on ebay buy-it-nows at lower prices. Or more guys selling it, or lower final bids... They all influence each other. But I like my system of what to buy, I have made profite on 98% of what I bought, sometimes 3 and 4 times what I paid they are worth now... So yes, you can do the math anyway you want, I wil ldo it my way and be happy... Also another thing is that many of the sellers on those other sites such as amazon are made up of guys who have physical shops in the u.s.a. or wherever. Not "ebay shops"... So they have an influx of ppl walking in and out of their stores daily. There also seems to be a bigger portion of liars on there, and guys who will put down any descriptio nwhatsoever for items and think they can rob you. because they usually won't respond to any of your emails and they ignore you until you make the purchase.. High prices, and dishonest sellers don't mix...
