You can buy an item for $20 at a store within walking distance. you can buy the same item online for $12 with $10 for shipping. which is the better deal?

To be honest, I think that depends on the person. If they don't want to get up and walk to the store, then the online item might be better. Online, it's $22.00, but at the store, it's only $20.00. For me, the better deal would be the item at the store.
