Looking through the free RPG day bundle, it looks like the only way to download things is to expand each product and click each file individually. Have you put any thought into a bulk-download option? Especially for bundles, but also for when a product has 10+ files - bump in the dark has many, and this would be a boon for us packrats who want a full archive of our library.
I agree completely.
I do have to say, though, that publishers need to learn to use archives (such as zip) when there are more than three files in their product!
We’ve added a quick single ZIP file download for all products - you can access this from your order page and your Library.
We don’t currently have a single download for an entire order or entire bundle, as we were hitting issues with the ZIP file generation for 250 products consuming too many server resources 
While we continue to work on that, you can at least download each product with one click for all your orders, not just this bundle.
It looks like the PDFs zipped this way are locked and cannot be opened.
I noticed this too – not sure whether it’s a macOS-specific thing, are you using macOS?
Thanks for flagging this. It looks like that was caused by the archive library we were using, and we’ve fixed it now. You won’t see that issue again with the bulk downloads.
Sweet. Thanks for the quick response!
There is still no way to download the whole bundle as one ZIP file, correct?
Correct. Once we can establish a way of doing doing that that doesn’t crash the server, we’ll make it possible.
