When to buy Santa Containers? 1. You like the ships on the short lists. 2. You own a metric crap-ton of tier V and VI premium ships. When to PASS and not buy Santa Containers? 1. New players. If you buy, random boats are likely to be low tier and not as good a value as somebody with those ships already in their dock. In summary, buy for the shortlist and enjoy the extras. If you are not a whale, buys beyond those shortlist ships will lead to buyers remorse.
