Inexpensive ideas:
Toy Lending Library - Free for your first visit, max of $10 for family after that
E2 Toys 2 Try - $12 per family max to play
Arsenal Lanes - Saturday special - $7 all you can bowl 12-3, Sunday 1-4 $6 entry fee then .50cent shoes, games, etc.
Chuck E. Cheese - Print coupon for 100 tokens for $15 and it'll keep you busy a couple of hours
Carnegie Museum Natural History/Art - I read somewhere that February was "kids free" month. I can't find it on their site but I know I just read it. A bit more expensive ($15 per adult) but a good deal.
Glow in the Dark Mini Golf - At Pittsburgh Mills. Kids are $5 or free with a paying adult ($6 adults). Then wander around the mall, play in the hobby store/train table, ride the carousel ($2), visit the pet store, etc.
