Buying coins in pvz garden warfare 2

Microtransactions for coins have not yet been implemented into Garden Warfare 2. They will be coming in time, but if you're looking for some quick coinage, I'd recommend going for character promotions (reaching level 10 with a character will grant a 20,000 coin reward) or going Gnome hunting (if you're up to the challenge!).

Edit:

Coin packs appear to have gone live since the time of my post. More information in this thread.

Is it possible to buy coints in pvz garden warfare 2 now? Did they fix it? I tried dotpay and paypal, and nothing works.... I tried directly from the game.

I have seen a few reports of difficulty with the coin purchasing system in recent months.  They are shown in the PS store, but I haven't tried purchasing one.  I haven't had any issues with purchasing the game upgrades, though.
