I subscribed before everything started and have gotten all of the American releases so far. Fortunately I haven't had any of the ships arrive broken or mangled (My TMP Enterprise saucer is attached at angle though).
Their schedule with me is that I get my ships second week of the month and pay for the next month the following week. Everything is always on time too.
I am confused as to why I haven't received an email about the NuEnterprise special though; Thought it would be coming out in April since the Brits got theirs in March.
