Walmart has a great deal on a train table. You can pick one up right now at Walmart for only $59 shipped! This is not a name brand table, but is great if you are on a budget.
Of course, if you want the higher end one from Kidcraft, you can grab that one today for $118.99 shipped over on Amazon! Remember that on Amazon, many states do not charge sales tax so it can be a better deal than getting it from another website!
