You have not lived until you've tried to buy groceries on a budget. Although my petitions for it to be added to the 2020 Olympic Games have been for naught, this is sport at the highest level.
On one hand, you want to treat yo self. It's been a long year for a lot of people, and splurging a bit on groceries can be a bit of a release from the hellish firescape that is 2018.
On the other, those Hulu, Netflix, HBO GO, and NBA League Pass subscriptions ain't gonna pay themselves. Flexibility is a necessity.
