I was just out at Party City in the Barnes & Noble Plaza out on the Benner Pike in State College. They still have Santa suits in all price ranges (from $39 to $99) along with tons of accessories to stylize your outfits – elf and Mrs Claus suits too.
If you do head out there, don’t forget to take advantage of the 15% discount available to all Santa Crawlers (use the coupon at this location)
