Here, on the frontier of consumerism, you can...
1. Pay the list price for a book, and not the jacked-up local currency price which they print on a really gummy sticker and mask over the list price hmm I wonder why that is...
2. Order your groceries and have them delivered, and I don't mean using Fresh Direct or some other specialty service - you can literally call your own corner grocery store and tell them to bring you a can of chipotle peppers in adobo sauce what you forgot not 5 minutes ago when you were down there damnit.
3. For that matter, you can have a coffee delivered. I said "a".
4. PUMP YOUR OWN BUTTER ON YOUR POPCORN FOR FREE FROM THE MACHINE THEY HAVE RIGHT OUT IN THE OPEN NEXT TO THE STRAWS AND NAPKINS
5. Buy a $20 cell phone and fill it with minutes from a different cell phone company every month.
6. Get your dog a membership at the dog gym.
7. Go to a quaint little arthouse cinema on a Tuesday afternoon and watch a truly terrible little arthouse film.
8. Go to a club that only sells "bottles" and drop a minimum of $1000.
9. Go to a restaurant that serves nothing but PB&J sandwiches ("Peanut Butter & Co.", 240 Sullivan St). Or rice pudding ("Rice to Riches", 37 Spring St). Or macaroni and cheese ("S'MAC", 345 E 12th).
10. Leave your wallet at home and just soak up the sights, smells, and sounds of this fabulous city.
That last one is bullshit. You can't move in this city without spending money.
