ebay isnt market value

Ebay may not be market value but it most certainly is a factor in determining market value and should be considered in a price guide.

If you assume that a price guide is showing you what a card is selling for (i.e. price) I would think you would consider what that card sells for at shows, in stores, online, etc. and get an hi-lo range based on those factors.

I find it hard to believe that is done anymore, there are just too many cards which makes you question the value of a price guide.
