The future is here. You can access the breadth of human knowledge with a small computer that you carry in your pocket robots can do surgery, and you can get just about anything delivered to your front door with the push of a button.

Whether you're looking for a specialty item or just trying to get your grocery shopping done, what sort of things can you now get delivered to your door?

1. Printer Ink

Keeping up with your printer ink needs can be a daunting task. It's easy to ignore your printer's low ink alerts right up until you run out of this liquid gold and have to make a mad dash to your local office supply store to buy more.

HP has come up with a solution to this incessant problem--Instant Ink. This program, which only costs a few dollars a month, allows your printer to order ink cartridges as soon as your ink levels get low.

The ordered ink is packaged and delivered right to your door, making it simple to keep up with your printing. As a bonus, HP's Instant Ink program saves you money -- up to 50 percent on the cartridges themselves. Ink is expensive even at the best of times, so if you utilize HP printers and want to save money, consider enrolling in the Instant Ink program.

You're paying extra for that convenience though -- if you print more than your monthly page limit, for example, you could end up paying a lot more than you would just heading to your local office supply store to replace your ink or toner cartridges.

Canon also offers an Easy Ink Delivery service for their compatible printers, but it does require you to click the "Order Ink" button.  In some cities, you can even have your ink delivered same-day when you order from office supply stores like Staples. This is currently only available in Boston, Chicago, Dallas, and New York but they're expanding their service area every day.

2. Massages

Scheduling a massage is a great treat, but it does require you to go to a massage therapist's office--which isn't always convenient if you have an odd work schedule or don't have the time or transportation to make your way to your appointment.

This isn't available everywhere, but if you're lucky enough to live in one of the bigger metropolitan areas that are serviced by apps like Soothe and Zeel, you can order a massage.

Sooth, for example, offers 60, 90, and 120-minute massages, with therapists-on-call who can be at your home within an hour. Currently, it's only available in major cities throughout the United States and Canada, but they are expanding their business every day. It might not take too long before you can order a massage in your hometown.

3. Medical Marijuana

It's important to note that this service is currently only available in Texas. Starting Feb. 1, medical marijuana patients in the state could order their medicine and have it delivered directly to their home. This is a great tool for anyone who uses medical cannabis but doesn't have the means or the capability to travel to their local dispensary to obtain their medication.

Medical marijuana is currently only legal in Texas for patients who qualify under the state's Compassionate Care Act--so it's limited to patients with epilepsy who don't respond to other treatments--and the marijuana has to have a THC content of less than 0.5 percent.

4. Laundry

Everyone loves clean clothes, but no one likes doing laundry--so why not have someone do it for you? If you live in Chicago, Washington D.C., Boston, San Francisco, or Los Angeles, you can do just that with a handy little app called Rinse.

This app connects you with on-demand laundry pick-up and a wash, dry, and fold service. There's a three-day turn around. But if you need it quicker, you can pay an extra $5 for rush service. Not too bad for $1.75 per pound of laundry, free pick-up, and $3.99 delivery.

They even handle dry cleaning, which is an added bonus.

5. Anything

If you can't find an app to deliver the exact thing that you're looking for, why not look into an app that delivers everything? If you live in one of the cities they service, Postmates can bring just about anything to your front door with the touch of a button.

Order a pizza from your favorite pizza place that doesn't deliver, medicine from the local pharmacy when you don't feel good enough to head to the store, or even tools from your local hardware store. Just make sure you're specific, so your delivery man or woman is able to find exactly what you're looking for.

More Home Delivery Options

This is just a small sample of the stuff you can have delivered--order Lootcrate for pop-culture-related items, Blue Apron for pre-made meal kits, or Winc for a new bottle of wine delivered to your door every month.

If you can think of it, there's probably a service out there that can have it delivered to your front door.
