The TV I purchased from Walmart last week has been marked down $100 for Black Friday. Can I get a refund? - walmart sanyo eneloop canada

I bought a plasma 50 "Sanyo for $ 698 Wal-Mart last Thursday. Now they've dropped the price up to $ 598 for Black Friday shopping. I do not plan to get up early and stand in line for hours to get the case, but I a refund for the difference?
