We don't know if there will be reruns. If there are, they will likely be selected episodes from the end of the season that will air in August/early September; at least, that's what happened the last couple of years. Since DVDs usually don't come out until September, iTunes is probably the best bet if you want every episode.
LOL, true! Having done the full series rewatch (s1-3), now I tend to rewatch only the ones I care for, and forget that there are other episodes in the series. My bad!
Anyhow. I'll be following the rewatch comments to share on the ones I watch and find out which eps I should also add to my list.
