Mastermind is a good place to go if you're stuck getting a birthday or Christmas present for someone else's kid(s) and have no idea what's in right this minute, let alone what the kid might actually want. Finding quality, old fashioned (i.e., non-electric) toys is tough, and this expanded Mastermind will give you some options.
It's probably best for kindergarten to grade 3 or so, since the toys are a little too convoluted and "educational" for toddlers, and a bit too lame for budding preteens.
I suspect some of the toys here (like the enormous stuffed elephant in the storefront display costing hundreds of bucks) are more likely to spoil a child than smarten him up. And I doubt the educational value of a Transformers chess set. But most of the stock is suitably high-minded.
