Maybe someone can help. I purchased a bluetooth speaker on Amazon on Nov. 30 to give to my mom for Christmas, and now that same speaker is marked down by $30. Does Amazon retroactively apply discounts if you contact them and make a stink? If I request a return slip and mail mine back tomorrow and immediately purchase one at the sale price (assuming the deal is still going on), will that raise any eyebrows on their end?

UPDATE: Got dat refund, though they did give me crap about being a day outside the 7-day window for this kind of thing
