From January 5-11, Toys R Us America will be offering $15 off when you spend $60 or more on LEGO Construction sets (reg.$3.99-$149.99). Many items have went back up to the usual Toys R Us markup prices so be aware of that when your shopping. Some sets you may get it slightly below retail if you buy sets with the least amount of markup and you buy as close to $60 as possible. Remember you can always compare the MSRP prices at LEGO Shop at Home.
A few sets like Friends 41057 Heartlake Horse Show ($39.99) is still at MSRP regular price without TRU markup.
