Amazon says the original retrieval pricing matched their cost, but was hard to grok and easy to run up a huge bill if you didn't use it carefully and extract data patiently.

They realized that was a mistake and significantly streamlined the pricing, and with this Deep product it doesn't look like they've even supporting the original somewhat opaque Glacier API, just S3.

If you're patient and can wait 48 hours for data, bulk storage retrieval is cheap at $0.0025/GB and $0.025 per 1000 requests. The standard AWS $0.09/GB egress is the really big cost, but if you have enough data you can mitigate that with a Snowball. Not a big issue if you're recovering from a catastrophe that destroyed all your local backups, it looks great as insurance for those of us with modest time to recovery desires.
