Last night my friend brought me the "deluxe" cubes. They came from:
Ckoach House Cards and Gifts
Sunnyvale Town Center
2502 Town Center
Sunnyvale, Calif. (address from phone book - it may be inaccurate)
They had the cubes there for $3.95 per cube. They were made in Korea, I
forget the brand name. Coach House was also apperently selling the regular
cheap-type cube (Wonderful Puzzler?) for $1.10 apiece. A good price.
