The customer support is helpful and friendly as well. I have not found a better company for keeping track of your items. I also use their Music and Book databases as well. They even have a Comic Collector app as well.

NCBD! Big comic week! No surprise to seeing this issue being the most populair title this week: Marvel and DC are teaming up with their Spider-Man / Superman crossover. Image is releasing 3 new #1’s. Here are a few books that were handpicked by our content managers:
Head Lopper #1 New volume, new heads that need to be rolling. Witness Andrew Maclean’s masterclass in kinetic action and dark humor. Looking forward to seeing what Andrew has in store for us with Norgal in 80 pages of comic-goodness.
Marvel / DC: Spider-Man / Superman #1. This has to be THE biggest crossover we’ve had in ages. Continuation from Superman / Spider-Man, has you exploring this crossover with multiple different characters across both publishers. Tons of covers, with the Peach Momoko being the most notable for me. Which cover or covers are you getting?
All comics releasing this week can be found in the NCBD tab in your add comics screen. All new releases have been carefully cleaned up, with lots of info added! Be sure to check them out in the app. Either when you hit your comic shop or, when back home adding your stack you’ve just come home with!

Another week, another NCBD. It’s no surprise here, that Absolute Batman #19 is the biggest book this week (as can be seen in our Most Wanted on Monday). No less than 54 different covers for this issue! Absolute craziness? Our content managers might even have to be send to Arkham Asylum after adding this many into Core. Don’t think we’re done yet. Image releasing their new series: Fireborn. A bit of a smaller week for Marvel… Here are a few books that were handpicked by our content managers:
Radiant Black #41 Are you caught up with this series? I sure am! Horizon is Chicago’s hero. Radiant Black needs Shift’s help to sneak into a lab that’s withholding secrets. Will they succeed?
Absolute Batman #19. This issue brings us the introduction of Slade Wilson, Scarecrow and the Robins within the Absolute universe. This should definitely be a solid after we know what were getting next issue.
Cheers, mate! After a bit of waiting, we’re back with a new issue of Redcoat #17. This should be a nice set up for what’s to come. I’m especially fond the Kyle Hotz cover!
