Amazon has a sweet deal on the Melissa & Doug 100 Piece Safari Floor Puzzle! Marked down from $12.99, they have it for just $3.88 + $1.99 shipping! This is the best price I have seen on one of their floor puzzles, so make sure to snatch on up before the price goes back up!
This puzzle is over four feet long, and has extra-thick pieces are 20% thicker than other puzzles. It also has a 5 star review!
