Here are some suggestions for the Shop Filter:

Special Items - Only Special Items appear
Item Available - Only items that are available show up (Very useful for Special Items filter.)
Currency Type - What currency the item is worth; Bucks or Bits.

That's all for now, I might add more in a different post or make a new one.
