I can’t speak for Best Buy though I’d say they have to honor it. MSRP should be honored as well as a sale offer.
Once Best Buy tried to pull this nonsense a while back and I pushed to get the price honored. Apple dropped the original watch price and Best Buy had a sale that week advertising $100 off the watch, not a specified price. Since Best Buy is an official apple store, they had to honor the price drop and advertised sale offer.
If it is honored you can get a PS4 Pro + PSVR GT Sport Bundle for $400
