I have several hundred bike-related purchases on Ebay, but my activity level has slowed to a trickle. I only buy through auctions, as the BIN prices are almost always more expensive that I can get the product for direct from Asia or Europe. The over-valuation of the US dollar probably has a lot to do with this. Bike stuff, including complete bikes should be dropping in price, as the dollar appreciates relative to other currencies. But don't see this at the street level.

Another significant downside to Ebay is the relatively new: 'Global Shipping Program' which pegs extortionist 'import charges' on cross-border transactions. These charges are multiples of the actual taxes and duties that are actually due to the Feds. I assume the couriers just pocket the difference. So I never bid on these.
