Looks like the 1st LEGO Cuusoo/Ideas set is now really going away for good! It has been listed as “retiring soon” on LEGO Shop at Home for quite some time and now, it has been discounted by 20% off. Available for $27.98 USD (reg.$34.99) or $35.98 CAD (reg.$44.99) at LEGO Shop (USA and Canada). Free shipping on orders above $75.
Amazon.com also has it discounted for $27.98 USD (reg.$34.99) as well. Thanks to forum member Marcus70 for the heads up! (thanks also to Will for writing in)
