At the Harris Teeter (supermarket), my favorite ice cream was on sale. I had already gotten a cake that was also on sale. To return the cake to its cooler would have required traversing the entire store, so I was forced to keep both desserts though I had intended to only buy one.
Same with the alcohol. I had already been to the liquor store for a large bottle of my favorite tequila. At the supermarket, my favorite beer was on sale. I was forced to get double alcohol.
I saved a lot of money today.
