As you see, the $100 off is already displayed. But if you are going to go cheap on cost, there are two choices. The Asus Vivobook X202 or the Vivobook Q200. DO NOT BUY THE Q200, buy the X202. I don't have either of these, but the X202 is the superior version.
The Q200 is the BestBuy exclusive variant that was suppose to be cheaper by $50; why the are the same price now, I have no idea.
