EITHER......

Too many
Not enough
Too tough to get
Not truly promoting the product
Too many made
Not enough made

The list goes on and on.
Bottom line, you can't make everyone happy.

I guess this hobby shouldn't be referred to as Trading Cards though.

Or in my case too disorganized and time limited to place them out to trade!

How about these ?

Cards that actually advertise the product (thus making them promos, in my opinion) but are never made available at shows, for free through dealers or thrown in with a purchase, or from the company itself, but instead are given to a handful of dealers who automatically put them on ebay, and unfortunately are otherwise unobtainable.

Variations on promos (foil, enhancements, etc) that are given to dealers 1-2 years after the regular promos come out, as incentive cards
