No, you didn't do anything wrong. Target's website isn't currently connect to Shop Your Way, and that's why the price isn't updating to the current price. Sorry about that. You might be able to get Target to price match it.
Go to sears.com, search for something, select the Sears Only tab for items Sold by Sears. For some reason, items that are discontinued are removed from Sears.com but remain here. You are more than likely viewing discontinued items.
