CHICAGODrug addict Chris Fehring, 27, announced plans Monday to eventually buy back the GE toaster he'd sold an hour earlier to U-Name-It Pawn. 'This is only temporary,' said Fehring, who'd already parlayed the $3 he received into a crack purchase. 'I'll buy it back as soon as I have electricity again.' Fehring also stated his intention to buy back the blood he sold to the plasma center Monday.
