skip other iptables marking if packet is already marked

I have many iptables setmark commands, but as soon
as there is one match, I would like to skip all the rest.
How to do this.

-------not-working-not-mark-zero-is-not-accepted---------

iptables -t mangle -A PREROUTING ..... -j MARK --set-mark .....
iptables -t mangle -A PREROUTING -m MARK ! --mark 0 -j ACCEPT
iptables -t mangle -A PREROUTING ..... -j MARK --set-mark .....
iptables -t mangle -A PREROUTING -m MARK ! --mark 0 -j ACCEPT
iptables -t mangle -A PREROUTING ..... -j MARK --set-mark .....

--------------------end-----------------------------------

Since it is not working, I change it to :-

Assuming I have AND-ed all the mark together to obtain the MASK,

iptables -t mangle -A PREROUTING ..... -j MARK --set-mark .....
iptables -t mangle -A PREROUTING -m MARK ! --mark MASK/MARK -j ACCEPT
iptables -t mangle -A PREROUTING ..... -j MARK --set-mark .....
iptables -t mangle -A PREROUTING -m MARK ! --mark MASK/MARK -j ACCEPT
iptables -t mangle -A PREROUTING ..... -j MARK --set-mark .....

Wonder if it will work ? 
My next question is should I use -j ACCEPT or -j RETURN ?
