I was wondering if I went to a store a day or so before BF, found an item I know will be on sale, then hid it behind other items, or even put it in a different part of the store, then returned on BF and retrieved it.
Of course, there's always a risk a clerk could find it and return it to its spot, but has anyone ever tried this, especially in cases where a store may not do price adjustments on items purchased before BF?
