One of the first people I sent a package to hasn't posted to AnySoldier in over 50 days. They dropped her name yesterday. I hope she is alright.
I think that probably more of them write than don't.
Coffee, should I send instant, the bags of grounds or the single serving ones that come like tea bags? My grocery store sells the small one pot flavored ones often for a really good price!
All forms of coffee are welcome. I think it's safe to make the assumption that large groups have the ability to brew pots of coffee, especially if someone asks for filters. I checked the price of the teabag-style ones and the premium was enough to deter me from buying those.
Instant is a good idea, especially instant espresso and the more unusual flavors like hazelnut. That is a particularly nice thing to send if there are females in the group. Also flavored powdered creamer.
I can get Italian-branded half pound espresso bricks for a dollar. Those are going to my Medevac fliers. I've sent some Goya espresso to a Hispanic marine who turned out to be from the Bronx!
There is a Greek Nescafe instant iced coffee product available in my neighborhood that I might think about sending when the weather gets hotter. That store used to have small, battery-operated mixers that you would fill with ice, water, milk, sweetener, and the powdered coffee for a frappuccino at a fraction of the price. If they have those I might get some.
