ZamZam have the model to follow for vinyl only/limited one pressing. Their first releases were 500 then when demand went up they started pressing 600.. 700.. now they press like 900/1000.
Still limited enough to keep it tru head but just rising slightly as their demand and popularity rises.
In terms of Bandulu they could have done 500 for 1-5 then 6-10 say 600, or 750. W/E.. just reviewing it regularly as demand increases. Its not difficult and would avoid all this agro + more P for them + keep it tru hed limited.
