What's the Difference in this Memory?

Newegg has the two following sticks of RAM for sale. I can't tell why there's a price difference and if the two are different in any way. Anybody know? I ask b/c I installed the $77 version (works great) and I ordered the $65 version yesterday.

KINGMAX Memory 256MB PC2700 DDR RAM Model# MPMB62D-683 -OEM $65


KINGMAX Memory 256MB PC2700 DDR RAM OEM Model# MPMB62D-68KX3 $77 (not in stock)

Newegg does that a lot. When they change prices after an item runs out, they often don't simply change the price but instead make a new listing for it. Don't ask me why.
