I wonder, legally, if there is a difference between the companies that simply raised prices, and the ones who kept the price the same but added another line item to the invoice that covered the tariff.

IANAL, but for the former, it seems like the company may be entitled to keep the money (of course it’s morally wrong). For the latter though, it seems like maybe (???) there’s some stronger legal pressure on the companies.

Or not. But at least CAH is doing the right thing, as others have pointed out!
