It's official: Black Friday has transcended both space and time. No longer bound to the Hipparchian constraints of the 24-hour day, the Mother of all Sales has now given birth to an entire generation of equally stygian offspring, oozing her mercantile tentacles into nearly every crevice of our American existence. Case in point: Target's pre-Black Friday sale. It's a sale in honor of a sale that's in honor of a holiday -- the Apollo to Thanksgiving's Jupiter, if you will. It's also where you can grab a Nintendo 3DS for just $145, as noted in this ad that we came across yesterday. So loosen those purse strings and clench your fists, because the Supra Sale draws nigh.
