Obviously made up. In store pick up does not allow same day pick up, you have to wait for it to actually be shipped to the store, even if the store has that product in stock. It comes from warehouse stock and NOT store stock and they don’t allow you to pick it up even if it was right in front of you until it ships from the warehouse (I know, I went through the same ordeal before).
I don’t know how many places this would work at seeing that most places with in store pick up take at least a couple hours. However this does work at Toys R Us. I do this all the time, because they rarely stock the shelves in their stores. If I can’t find the item I want I just go to toysrus.com and order it with in store pick up. Out of all the times I’ve done this they have never taken over 30 minutes to have the item ready.. And it is usually about 10 minutes.
