Comics and graphic novel sales to comic stores showed another big decline in March, but given the quirks of the calendar (five months in March 2017 vs. four months in March this year), the month may have been the best of the year so far according to numbers released by Diamond Comic Distributors.  Comic sales were down 13.2% and graphic novel sales were down 22.12% in March vs. March 2017, bringing the total decline to 15.96% for comics and graphic novels combined.  But the 15.96% decline is roughly what one might expect if sales on a weekly comparison were about flat, so we read these numbers as an encouraging sign that March was a better month than the first two. 

For the quarter, comic sales were down 7.09%, graphic novel sales were down 13.17%, and overall comics and graphic novel sales were down 8.92%.

Share numbers were much as they’ve been in the past few months, with a relatively narrow lead for Marvel
