Incidentally, what were the values of those other three gifts -- the ones given back? Might make interesting conversation to see just how many ways there were to win, since G/K and Finish Line were games where you could make a mistake on one or (albeit very rarely) even two and still win.
Here's what I was able to find...
First pair:
Paint: $27 (Horse)
Dish: $19 (Finish line) (the eggcrate erroneously showed $11 for this)
Second pair:
Yogurt maker: $17 (Finish line) (the eggcrate erroneously showed $28 at this point; should've read $36)
Clock: $25 (Horse)
Third pair:
Sealer: $26 (Finish line) (the eggcrate erroneously showed $54 at this point; should've read $62)
Decanter: $30? (Horse) (the eggcrate erroneously read $77, should've been $82, I believe)
Edit: Are images disabled here? I've got a screencap of the board at the end of the game, was going to post it. The red number next to "decanter" looked fuzzy to me, but I think it said $30, wanted to see if anyone else could get a clearer look at it.
