I hear better things about Target and Walgreens than I do about CVS and Rite Aid, but I can't speak too much in this aspect as I have not had an intern job, just rotations. I did a target IPPE in 2010 and I really enjoyed it-the pharmacists were great and friendly and really helped me learn, the environment was not too overwhelming and they really took time to help the patients out in the aisles too for OTC meds. This was in 2010 and I just did an APPE in 2013. While I think the script count was still not as overwhelming as say CVS or Rite-Aid, I really the environment was increasingly tense which was reflected by the behavior of the pharmacists as well and I've heard it's becoming more or less worse. lol. I hear good things about independent chains, grocery chains, I guess the script count is pretty manageable.
