Nordstrom's sale credit policy has changed and is terrible. I work during the week and just noticed the new boots I received February 14 went on sale. Called to be given credit for the reduction on February 16 and was told since they no longer had my size in stock they could not give me credit. I asked them how they knew that they were out of my size when the sale started (which would mean I coincidentally bought the last pair), and they said it didn't matter, as long as they were out of my size at the time I called I could not receive credit for the sale price. Returning the boots.
Someone else will probably be able to buy them on sale.
