Today through August 23rd (Friday), TRU has the Calvary Builder set from The Lone Ranger is $9.99 (TRU price of $16.99 and MSRP of $12.99).
Looks like you can order on toysrus.com, and if you buy at least 8 of them, you get free shipping! (or buy a few other sets – the whole Lone Ranger series is on discount… but aside from that and Ninjago right now, when TRU has a “Sale”, it just means they dropped their inflated prices down to standard MSRP…)
