If you're out shopping and want to find the best deals, there's actually a spot in the store that is typically designated for all stores to keep the cheapest items.
If you walk into the store, you might want to head to this area:
THE BACK LEFT CORNER OF THE STORE
Pretty much every store, grocery stores and retail stores, will put the high-ticket items on the right side of the store because shoppers naturally turn that direction first. The less expensive stuff is in the back left where you're less likely to find it.
