I remember a couple of months ago i found the Greatest Battles two packs discounted for $3.22 and Target two packs exclusive for $6 at my local Target. It shocked me...bought the entire waves of Thor/IM, Spiderman/Sentry, Dark SM/DWolverine (ultimately exchanged it for the secret wars Magneto/Black Costume SM), Cyclops/Dark Phoenix, etc. Picked up an IM/Black Panther box. I hated this Black Panther sculpt so i had to buy the regular single card. The individual version is becoming one of my favorite figures.
Then i excitedly drove around to the other Targets to find it was my local one discounting them only. Either way...a great haul at the time.
