Walmart offers the
Meccano Super Construction Set for $72.09. Choose in-store
pickup to cut it to
$28.79. (For Prime members only,
Amazon charges the same with free shipping.) That's tied with our mention from three weeks ago and the lowest price we could find today by $51. This 638-piece set includes a 6-volt motor and can be built into 25 different models, such as a helicopter or buggy.
