your friend is at work and mentions they're craving a chocolate chip cookie? $5. your brother is sick? $10 with the soup emoji. sometimes you cant deliver a present in person and this is the next best thing.
my friend once hand delivered mini tiramisus from a Japanese bakery after I vented and cried on a phone call.
I would recommend saving this strategy for once a year, for maybe your most patient and charitable friend as I imagine this could make you seem miserable or a pain in the ass if it happened often - maybe luck will reward you
