I was in my local Target today and noticed the colors they had for 2D's: Black, Silver and Copper. They had 4D's in similar colors but no 3D's. Their price IIRC was $17.99 for 2D's. I also noticed their price on Solitair's was $4.99.
I've been to two Targets in the last three days and both had 2Ds in blue, black, pewter and copper and 4Ds in black, pewter and copper. And I don't think they had any 3Ds at all. Down here, 2Ds are $16.98.
