We save almost US$0.25 per $1 transaction because of PayPal.
There is a reason why after all these years and other solutions they're still everywhere, and it's not because of their great tooling, their low fees or their awesome support for merchant. It's not because of market lock in either, at least here in Europe they're merely a middle man between my credit card or sepa bank account and the merchant. It's because buyers trust it.
Buyers don't trust stripe. Stripe is for the merchant.
I will never use PP for a large purchase again.
We had many customers that would buy a 1 month sub then chargeback the whole amount after using it heavily for a few days, with a nonsense reason like "item not as described" or "unauthorized charge".
I have had PayPal work for me for refunds many years ago, but the problem is often how long the whole process takes and how long your money is held hostage. By the time you maybe get your money back, you've already had to pay off that money on your credit card (if you used credit for the PP transaction). I've found that when I do a chargeback via my credit card, they often give me the money back right away and then do an investigation. If it were to not go my way the money would get taken back. I think this feels more fair depending on the case. Some cases are pretty clear cut and there is no reason to hold your money hostage while they confirm what you said is truthful.
If you want purchase protection you need to use a card that offers it.
But yes, it's my mistake for assuming the purchase protection would... protect my purchase.
And now I won't make that mistake again. The value isn't there, neither with their aggregation service nor their credit product.
I can just use Google Pay with a credit card, both of which are more convenient and offer better protection than PayPal does respectively.
I did until October 2022, when PayPal published an update to its Acceptable Use Policy that threatened to fine users $2,500 for promoting "misinformation".
Like they were the arbiters of what is misinformation and worthy of economic penalty. While it was later rescinded, it was beyond the pale. It's proof that something is corrupt and completely out to lunch in their management, and I won't sign up again after deleting my account in protest.
Edit: So apparently they only removed the misinformation clause, and they may still seize $2,500 of your money if they alone decide you are guilty of "...the promotion of hate, violence, racial or other forms of intolerance that is discriminatory or the financial exploitation of a crime...". People are worried about authoritarianism, yet meekly cede such powers to a corporation? It boggles the mind.
The libertarian answer is that corporations cannot threaten your freedom because you always have a choice of whether to deal with them or not.
The libertarian answer is also mostly bullshit, but there is a kernel of a seed of a nugget of truth in there somehow.
And as a consumer, I especially hate PayPal because they always try to screw me with their currency conversion rates by hiding the toggle button (and it happens that I sometimes forget to toggle over to my bank's currency conversion)
And only once have I ever won a payment dispute there (and that was as a merchant, not a buyer... lol)
