BO4 booster codes

Honestly, just a quicky
need some booster codes for Call of Duty Black ops 4.
safe

Are you looking to buy them or do you want to know where to get them? You get them with monster cans

i'm curious how easy it will be to get codes from monster boxes without buying them. During BO3 they had codes printed on doritos bags and you could just go into a big grocery store and quickpic a bunch with your phone in less than 3 minutes
