As you can see, most of the NJ rooms have signed up for this, including Party Poker!
Notably absent is WSOP.com.
I wonder how you get these, though? Where can you buy them?
If it's too much of a pain in the ass to obtain these, it won't really help traffic on these sites very much.
BTW, Citibank works great to deposit on these sites -- at least their debit card does. If you use the debit card, you don't get hit with any fees, and there doesn't seem to be any limit on the Citibank end.
