@MDidehvar - We’re planning on having all kinds of different packs. Our first pack was all the same type (pistols). Our next is this mixed pack. The one after it is PROBABLY going to be a Pistol 5 pack (the same as the 3 pack + the Desert Eagle and G18) and/or the Assault Rifle 3 pack (XM8, SCAR, SKS). No confirmed dates on these but we’re certainly planning to try to get a good number of both mixed or matched packs and of varying sizes to meet the needs. It seems for every person we get that says “I want a 3 or 5 (or more) pack” we get another that says “I just want to buy them one at at time as I need them.” So we’re trying to strike a good balance without simply flooding the marketplace with every possible option.
It’d be super cool if we could have a system where you could just pick and 3 or 5 or 10 and get a discount at the end 
But I don’t think that is going to happen anytime soon!
