I've been requested to create a 2019 calendar with about 150 copies. Gone to local printing services but they seemed extremely expensive ($9 to $10 a copy). Any recommendations for such services available over the net? Thanks

PS Print does all my media promotions printing.

They have calendars in several sizes & several print houses across the US for fast & not tooo expensive shipping.
150 is not very many.... you need to get into the 500 -1000 for a good price break.
