The Toys R Us I work for is up front about everything. If someone asks about it, they will tell them they will honor price adjustments for 14 days minus any doorbusters sales on BF (we actually call it Green Friday), but they could possibly do price adjustments for items later on in the day. The reason they do it is because it defeats the purpose of the doorbusters if everyone just buys it beforehand and then comes back in and price adjusts - because then they have to deal with people all ticked off that they waited in line and other people got something for the same price.
