Other than the usual toys from Toys R Us and Disney Channel/Nick Jr. Chanel cartoon toys which we have plenty off:
Lego Technic for older kids. Now they have architectural sets and some wicked vehicles.
Meccano sets - Meccano Maccanoid Robot
Anki overdrive racing track
Lincoln Logs
Science kits
Snap Circuits Jr.
Telescopes & Microscopes (these were not asked for but were a big hit)
Green Toys (simple but well designed plastic toys)
My nice and nephew are now10 & 12 so they just want clothes, cell phone accessories, gift cards…boring.
