I hadn't really thought about it much, but googling it looks like there's a discount programme for a committed spend of around $1M/year. For a small company, that's a lot of money, and it was an unusually large amount of bandwidth for the size of company. I suppose it makes sense now I know they're interested in companies spending that sort of money.

The trick is to use CloudFront if possible, even if not caching, just passing through requests.

Standard discounts start at 10 TB, which is not that much.

If not using HTTP, then it's a no starter.
