Well that was kind of exactly my point. It is in their interest to do gift cards because they don't lose anything or incur a cost on themselves, once someone is locked into a gift card they only gain sales.

This is made possible at least in part because they have savings on the credit card cut

I think you're not understanding me.

They have to sell it to retailers for less than they'd get after credit card acceptance. E.g. Apple sells gift cards for $88/$100 to a retailer, who then uses the remaining $12 on transaction costs (including paying their credit card fees) and profit margin.

Vs. Apple likely loses ~2% on credit card acceptance-- and gets to keep $98/$100.

It's still worth it, because they capture money from last-minute gifts, etc...

Hmmm yeah.

Though $88/100 is super unrealistic with margins on electronics of 1-2% Amazon would be taking a loss of what the profit from 10 laptop sales every time they dealt with someone buying a laptop all in gift cards.

Or maybe gift cards are so rarely used in this way they write it off with higher margin uses
