I bought two headphones Sony DR320DPVR and Sony MDRXB400B Headphones for $70 for both in the Sony Store in Melville WA. The DR320DPVR headphones were located in a 70% off box near the front counter for $35 which also had other discounted items. The MDRXB400B are a new item which retail for $69 in store.
After requesting cheapest price if I bought both they were reduced to:
DR320DPVR for $25 and MDRXB400B for $45
I'm not sure if you can use this at other stores to get cheaper price but worth a try
