Lowe's wants $45.17 for 100ft of 12/2 12ga ROMEX wire.
Local electrical supply (Denny Electric... kinda a regional chain) wants $36 ($0.36/ft).
I may have to drive an extra 10 minutes... but for $10 or so its worth it.
I'm not sure how or why I always associated big box stores with the best prices.... but on quite a few things I've needed in the past few weeks I have been pleasantly surprised at how wrong I was.
