Fiscal illusion

Fiscal illusion is like when things don't look like what they are. For example, if you buy something that costs $10 and the store says it is on sale for only $5, so it looks like you are getting a good deal, but when you look closely, you notice that you will also be paying $1 for tax. So, even though the item looks like it is only costing you $5, you are actually paying $6. This is fiscal illusion because the cost of the item is not what it seems.
