Summer of Love, a brand new Monkees collection from Rhino Records, is (at least initially) a brick & mortar retail exclusive, but some outlets like Bull Moose and Barnes & Noble are making it available as an online purchase. Bull Moose, however, is only offering the vinyl for sale while the CD is in-store only, and Barnes & Noble is taking orders for each version. FYE is another option, with both editions available online. At this time, Amazon has no stock of Summer of Love.
