Oh yes. 7" singles have been going through a major revival in the past 3 or 4 years.  Big, big with teenagers and the labels that are pushing them are making them very attractive in terms of packaging, a lot of small indie labels, downloads and vinyl singles are all they do. Nice gatefold sleeves, limited editions, multiple editions with different b sides, coloured vinyl, reasonable prices.  Its a vibrant chunk of the market and very definitely aimed at the "so you've got the download, now buy the real thing" vibe.
