Valentines day, Should I get Him a gift or not?

So i'm in a long distance relationship with a guy that lives 5 hours away and we really like each other and we are getting pretty serious now and a while ago i dared him to send me a letter but sense he lives in a gated community he can't send mail the way most people do so he'd have to go to the post office. And it's all the way across town, and he can't drive yet and his parents might be curious as to why he's sending mail. Is it ok for a girl to send a guy a gift/letter? (it's for valentines day btw) And what do you think is better to do? send a gift or a letter? And is it ok for me to send something even though he might not be able to?

Yeah I'm sure he'd appreciate a v-day card from you
