Toys R Us is offering 25% off all full priced items storewide until Sunday 24 November 2013.
The offer should apply to all LEGO products not already discounted.
Update: Some Whirlpool users have pointed out that LEGO is currently on sale at 20% Off, and therefore not eligible for the 25% off deal.
The saving should still apply to any items not already discounted, such as the LEGO Reversible Table with Storage Ottomans
