I've done it before at ToysRUs. They had the 4 pack My Little Ponies on sale for $9.99 last year on BF so I hid it and it was still there when I went back. Since I couldn't make it to the store on BF, I ended up buying it on their website for the same price. But apparently when I went back to the store after BF, they had plenty left so in reality, I didn't even need to hide it.
