If you missed the deal earlier last month, both USA Wal-Mart and Amazon now has LEGO Batman Man-Bat Attack back on sale for $16 (reg.$19.99). Thanks to forum member The-Daryl again for the heads up.
Also, the new LEGO Teenage Mutant Ninja Turtles sets are now available at various retailers including Amazon. Of course, keep in mind that LEGO is offering double VIP points which makes the deal a lot better.
