Yeah, Bandcamp limits the number of free downloads you can give, probably because they make 15% off profit. It's 200 songs, so only 67 EP downloads.
EDIT: I'm pretty sure the number restarts at the start of each month. I'll download January first.
The number gets reset on the 15th of every month. They boost it back to 200. If the band sells $500 worth of songs, then bandcamp gives them a 1000 credits.
