Games More Variants

I'm new, but I have already seen some wildly different prices on Castlevania 3. 

The link below has two variants, or should I say two options. 

First is the Castlevania 3 box with the Win A Trip... sticker on it, and the other is the fact that it has the Win A Trip card with it (very rare and sometimes sold separately). The card has an item number of KON-VN-US.

This is another one with a good picture of the Win A Trip card part #:

This link is to a standard CIB of Castlevania 3:

The pricing is wildly different between the Win A Trip box and no Win A Trip box, and the Win A Trip is a whole other level of rarity.

If anyone else has seen other variants, please post them here for everyone is use and also for Price Chart to start documenting them.
