Well, Comixology prices the Complete Battlefields volumes at $15.99 each, and Vol. 2 of that only takes you through 6 story-arcs of what's being offered in the HB, so as long as you read through 7 story-arcs, you'll have gotten your money's worth at the top tier even if Dynamite later holds a 50% off sale.
Speaking of sales, Comixology is holding the
Darwyn Cooke sale for up to 50% off assorted DC Comics titles of his (single issues), through May 16th.
Cooke is one of my favourite creators, and I would especially recommend The New Frontier and his Solo issue out of that. His Before Watchmen minis are also pretty decent (the Minutemen one is the better of the two, although the Silk Spectre one with story by him and art by Amanda Conner is also nicely done if you wanted more backstory on the characters), and so is his artwork in the Catwoman run written by Brubaker.
