D2D vs. IngramSpark

Not essentially the most artistic of submit matters, however I haven't been capable of finding rather a lot on right here instantly evaluating the 2 choices.

It looks like I’d make a way more important revenue per unit on IngramSpark as a result of they allow you to set the distributor reduce comparatively low, however I've heard some unfavourable issues in regards to the high quality of Ingram's customer support and communication (you need to pay them with the intention to truly discuss to a customer support rep on the telephone??) whereas Draft2Digital appears to have higher communication.

I additionally get the impression that Ingram takes out some small further charges whereas D2D doesn't? I could be misunderstanding that, although.

Does anybody have robust emotions in favor of 1 or the opposite? Has anybody switched from one distributor to the opposite?
