I don't do it at CVS very often unless my OOP is going to be alot. They call it "rolling ecbs or RR". I do it at Wags every week. When I do, I try to keep it at under 3 transactions but if they are busy I will step back and let others go ahead of me. At Wags I always try to use the beauty counter checkout. They seem to be more patient and helpful. Sunday I ended up with 5 transactions because I forgot about the shaving cream and then they brought out some scrubbing bubbles one step cleaners from the back. At CVS you don't have to worry about what you are using your ebs on so it is easier.
