I chain drink decaff Twinnings Everyday, have deliveries of coffee beans from Decadent Decaff and for at the Hackspace keep decaf Nescafe Azure. That mostly keeps me ticking.

Not all the decaffs are equal. That took a few goes. Some brands put a bit more care into it than others. And if you're shopping at supermarkets, I've noticed you have to go to the larger ones to get access to more than one brand on the shelf.
