Greetings, I have had many negative experiences at the CVS pharmacy in Littleton MA. It always appears that there is no enough help at the registers and waiting in line is very inconvenient. I usually pick up my prescription after work and it seems that there are very few people working on some of my visits so maybe they need to hire more help. I found that going to walgreens service is a little faster and I am thinking of moving my prescriptions there.
