For the record, I never felt like I was being blackmailed. Yes, you have to buy
something from them every year to keep your pictures safe, but that could be as cheap as a $0.12 print. And it's a great online photo album.
I've loved everything I've gotten from them, they're all very high quality and I've gotten good use of everything I've gotten. I've even given some of them as gifts (none of my Foster's stuff, though).
