Caviar is a third-party service that picks up food from local restaurants and brings it to your house/work/cave, much like grubhub, eat 24, seamless etc.
If you use my referral link, you save $15 and I get $15 credit. This is a conga thread, so you can do this too.
This is a great way to get lunch or dinner completely free. There are delivery fees for some restaurants, but the $15 credit covers it. I ordered 4 extremely delicious tacos and ended up paying like $.93, but it's possible to pay nothing.
An 18 percent gratuity is automatically included in the total, so you don't have to worry about any awkwardness. There is a "service fee" that varies depending on your order's cost ($2.38 for my order), but the $15 credit covers this too.
The $15 is automatically deducted at the end when you are checking out.
