i got none too...    guess we can be friends lol

Out of 84, I got none either, we can be the 3 stooges :)

let see, its only mine

the packs (vet packs and experts pack) are recieve at high rate
smoke bombs and phh recieve a mid to high rate
elite sailors, hq and ship tree reset low to mid rate 
medals,olive and coupon low rate

got 3 one is 1 bugged though trololol so all in all 2 coupons 

I've been around only for the last 6 days, and I spent 100 olive (which I got from this very event), so 25 box in total.

Got exactly one coupon, and I guess that puts me on the lucky spectrum.

Over 100 box no ebb, also two boxes has been eaten today. So unlucky

no ebb coupons for me

Out of 81 I got 1, and that 1 was during the second week of the event when I had around 24 boxes open.

640 vets 450smoke 560HH 6200 experts 4boosts 5HQ expansion 2 BO resets 1 elite pot 1 elite rep 600 olives 30 honor medals 3 ebbs Not a bad haul for free :)
Works out at  6060 olives, plus 30 honor medals and 3 EBBs, working out just under 280$ for free plus all the xp :)
and thats just on one of my accs 

I cannot complain about the amount of olives i got. Sadly i did not spend them during the event because yesterday it didnt work.

82 boxes gave me:

400 vets, 4800 experts, 400 smokes, 800 HH 4 boosts, 1 ship tree reset, 1 Elite engineer, 1 Elite Bomber, 800 olives and 50 medals

Out of 104 boxes, the number one item was 100x Expert packs, of which there were a whopping 15. Just behind were smokes and 10x Vet packs at 14 apiece. After that:

11 Expert x10

10 Vet x1

9 Boost

8 100 Olives

7 PHH

6 Honor Medal x10

3 Elite Engi

and EBB coupon, with 2 earned, is tied with Elite Bomber Pilot for 11th place out of 18 items

Below that were 1 each of HQ Expansion, BO Reset, & Elite Potential Sailor

I got no Elite Rep, Elite FP, or Honor Medal x5

By the way, calculating it, I saw a 60.6% chance of seeing a vet or expert pack, a 20.2% chance of seeing a ship item (PHH, Smoke), and a 14.4% chance of seeing a boost or elite sailor. Rewards valued over $3, honor medals, and EBB coupons combined appeared less than 5% of the time.

Edit: To tally it like the others are, I got 5200 experts, 480 vets, 700 smokes (!), 560 PHH, 800 olives, and 60 honor medals. Total value of olives & items that can be bought in the store: $316.50
