To expand on my earlier post, our experience with OPS [nearly a year] has been nothing short of horrible. The software is garbage, and the support is even worse. We've had several dozen serious failures of the core systems, and twice that many lesser concerns. We have support requests for major flaws and oversights that are still unresolved after nine months, have received several unfulfilled promises and have repeatedly been outright ignored. The software is so buggy and unrefined that it feels like a very early beta, and even if everything were working perfectly, the user experience would fall very far short of modern expectations for even modest ecommerce solutions. Our conclusion has been that OPS has put together a suite of services each of which "sort of" works - when you put them all together it sounds valuable, enough so that they were able to attract a major distributor [Kodak], but once you get into the nuts and bolts it completely falls flat. What they offer may be passable for small clients with small customers, but they simply aren't ready to be a serious player in the up-and-coming web-to-print and campaign integration games - and they don't seem to be in a hurry to get there. I would advise anyone who wishes to implement W2P and integrated email/web campaigns on anything more than a very limited scale to not waste your money on OPS.
