Amazon had a bunch of big sales in place ahead of Valentine's Day, but one of them wasn't very well thought-out. The sale offered good discounts on all of Fitbit's latest fitness trackers, which certainly isn't a bad thing. In context, however, the last thing you want to do is give your Valentine a gift that suggests he or she might need to get in shape. The good news is that Valentine's Day is over, but Amazon's big Fitbit sale is still going strong.
