I made enough for a 3rd Character slot, and additional Bridge Officer slot for my KDF. Now I'm almost 1/2 way for a new ship. Which is my next spending purchase. I might get a Tactical Vesta for my new Tactical Capt. Or a cruiser for my Fed Eng. Capt. Just have to see when I finally get enough.
Made enough to buy 2 extra character slots (I don't see any options for a single slot, only 2 and 4 slot options) AND one of the Vestas (though I have to admit I had a 1600z headstart on that one). I'd save up for the other two, but I keep finding myself buying lockbox keys for when I need that quick EC fix...
I usually spend it when I reach the amount needed for whatever item I want, so my stockpile isn't to high.
If I'd recap the items I've bought since S7 launched, I spent around 10k Zen on them, all of it from the Dil. exchange. (4x2 character slots, Vesta-bundle, Regent, Bajoran uniform, 1x 25 Doff slots and one or two support doff packs).
Hmm. Maybe 4k? Hard to say, since I was sitting on a couple k before the big selloff started, and have spent some since.... some doff slot increases, character slots, a costume pack (just before the sale, of course )
I'm planning on spending most of my zen, I'm just waiting for the winter event & my subscription to end, so I have a better idea of what things I need/want to buy. (inventory & bank spaces, EC cap, ships, keys, who knows....)
I spent as soon as I got enough to buy what I wanted. Quick math tells me that since S7 I've gained about 2400 Zen without putting much effort in. A serious farmer probably has the whole store bought out by now.
Im upto 15k exacually, i did have a little bit more but i spent 500 on a respec token after the fiasco with the changing of rep abilities like the shields and 250 on the uniform slots (250 for 2 extra slots for every character on the account is an absolute bargain to me), saves going to the tailor when you have 4+ outfits to choose from
Bought around 4.000 Zen on the dil exchange over the last 3 weeks or so, spent it on outfits, a ship and respec tokens. Still need another 1.000 Zen or so to get another ship I want but then I'll probably not bother with Zen for a good while.
