Why not just get a card without foreign transaction fees?

Because even with no fees, the rate your card uses to turn USD into whatevers will vary from card to card. If you're not paying an up front transaction fee, you're almost certainly getting rinsed on the rate offered.

Why not just get a card without foreign transaction fees?

Even among cards that generally use the mid market rate, the time they set the rate and their source will often differ, resulting in the differences mentioned in the OP. So if you feel it's worth your time, and if you can get up to date rates, you can still save a bit by using the card with the best rate on a given day.

Without real-time rates available from multiple networks, this relies on that back-tested effect that the card with the better rate tends to persist for several days; is there a reason to be confident that will continue? Not that there's much risk if it doesn't, but you could well just be wasting your time.

Nice trick, though not that practical.

1% of oversee spending may be to little benefit for the cost: 1. Get more than one card with zero foreign transaction fees. Make sure you won't get charged yearly fee on those.

2. On every transaction, check the rate on smarthphone. Oh, you want to buy $3 coffee, let me check my rate to see if I can save $0.03.

3. More cards is more monitoring hassle. Harder to track, more hassle if they get stolen and you need to block them all. Also payback program tracking is much harder.

4. Same with fees and interests. More card is more likely that you miss some payments and get charged interests/overdraft. One incident and you whole savings can go away. Even with autopayment you need to make sure you balance your accounts.
