I wouldn't bother buying Costa beans again, particularly when my other two options this week were the cheaper Noble Coffee (mentioned previously and a really nice brew) or my own roasts.
I had similar issues, and I found Pioneer beans to be excellent so I stuck with them. As you mentioned Costa don't put a roasted on date on their beans, or use bags with one way valves. The roaster is usually going every day, but you just have to hope that they rotate their stock properly. When I asked what the roasted on date was I got treated like I was a moron for asking. Also I had similar issues with blonding early, probably grind related, but at the time my rocky wasn't really up to scratch either.
