For me, CoRI's average payment time is about two weeks. They issue payments every week, but you are "paid" on the Monday following the next full week after your shop is approved, and the money won't hit your bank account until that Friday.
Example: If you do a CoRI shop today (February 10th) and it is approved today, you'll likely be "paid" on the 20th and have the money on the 24th. If it isn't approved until Monday (February 13th), you'll likely be "paid" on the 27th and have the money March 2.
