Costco has this notice on their online photo center:

"We appreciate and thank you for your ongoing patience - we understand the impact this is having on each of you! Through today, we've made significant progress toward re-enabling the Photo Center site; however, there's additional work to be done before it's ready to go live. We know the previous anticipated dates have come and gone, but we're doing everything we can to bring a safe & secure site back on line as soon as possible. With that said, we are now anticipating that the site will be back online within the next 1-2 weeks. Thank you again for your loyalty and ongoing patience.

"The current coupon book, mailed or found in the Costco.com app, offers $10 Off Canvas Prints, valid 8/6 to 8/30/15. While we are unable to take your order online, we can fulfill your order at the Photo Center kiosk in most warehouses.* For assistance, please check with the Photo Center staff."
