I'm not a huge holder in bitcoin. I've been buying a bit each paycheck for about 6 months so I'm up to 7 now. I have made a few purchases from Overstock myself and I must admit I've stopped purchasing things there because of the price drops.
Even when I did purchase things from Overstock I always repurchased the same amount of bitcoin. I think I've stopped temporarily because instead of buying those items on Overstock I've told my wife to not shop there for now because I use that money to purchase more bitcoin at these sale prices rather than acquiring more goods.
Once the price hits the 700-800 or more range, then I'll be in a more holding pattern and I'll feel more comfortable just making purchases in bitcoin and replacing what I use.
