Any aff company worth their crap(including copeac) does a standard 30 day payment cycle for low earning affiliates(<1k/month). Normally once you hit 1k you can request a payment that week and it will go through. Bank wires also can get sent much more frequently than checks.
We pay all US publishers net 15 and international net 30, we haven't made this public but have been doing this since the start of the new year. We also pay weekly for those doing over $1K a week. Hope this helps.
