I have sold 15-20 items on Ebay…some that I bought there in the first place. On 1/2 of all the items I sold on Ebay, I sold them for more than I bought them for in the first place, whether in the store, from mail-order, or from Ebay itself.
On the other hand, the best deal I’ve gotten on Ebay was a 2002 Specialized Allez Comp (E5 aluminum frame/Ultegra 9spd)…I bought the bike in November of 2001…YES, that’s before the actual model year…the bike was listed for $1999MSRP in stores. I got the two week old bike for $800. The owner bought it and decided to sell after just two weeks, which was highly believeable since the bike had JUST barely hit the market in the first place. He had decided to just order a Seven Ti frame, or something like that…at any rate, I got a BRAND NEW Ultegra 9spd bike for $800. I swapped the crappy Shimano 540 wheelset, bought a Cosmos wheelset at my LBS, and sold the 540s on Ebay for more than I paid for the Cosmos…making my total expenditure even LESS than the $800…more like $750 for a super bike.
I guess what I’d say about Ebay, is that it takes patience, and an understanding of the dynamics of how to list items…you have to know the types of mistakes people make in listing items…for instance…on the bike above, the guy had it listed in such a way that I was the ONLY guy to find the auction…hence the ONLY bidder…I waited…asked a couple of questions of the seller to determine the veracity of the listing, and, yes, sniped it for the $800.
If you REALLY understand how to list items, you can reap huge $…its annoying, but listing a Cervelo P3 as "Cervelo P3 P2 52cm TT aero (Trek,Litespeed,Guru) will get you hundreds more looks than simply “Cervelo P3 52cm”…remember…the whole idea is to get folks to LOOK at your auction…the more people that find it…the more bidders you get…and more bidders means a better bidding war at the end…
But when looking for deals…if you WANT a Cervelo P3 52cm…you aren’t going to get a deal on bikes listed as “Cervelo P3 52cm”…let alone if they are listed as I suggest…you are going to find the hidden deals by searching for things like “aero bike” or “TT bike”…although bidders are savvy to these searches now…it is getting tougher and tougher…so try misspelled words like “airo bike”…“airo frame”…etc…its all about finding the auctions that fewer bidders will find. And frankly, it is nearly impossible to find deals on Ebay for the absolutely most popular items…try getting a Dura Ace 10spd crankset for any sort of deal…and for that matter…Cervelos of any sort are nearly impossible to get super deals on. That doesn’t mean most of the Cervelo auctions aren’t worth most of the $ they go for…but you aren’t going to find a Cervelo going for less than 50% of the original price if it was made in this century…
Above all, PATIENCE is needed…it might take several months or even a year to find a deal on that highly coveted item that you simply can’t pay full price for…only you can answer whether or not that is worth it to you.
