I actually don't know, I sold my Shopify ecommerce yesterday because of this reason. So sick of aliexpress dropshipping with shit shipping times, customers, scams etc. Luckily I found an even better niche with digital products, 100% profits and zero shipping time. Unfortunately I only have PayPal for the moment.
If you find one, PM me please.
Yeah, but also no.. When I disabled Stripe a few weeks ago and only left PayPal, my sales dropped at least 50%. Having a card provider is important, not only for accepting cards but also for trust factor.
However this is exactly what I'm doing now. Only PayPal. If someone does a chargeback on me now I technically won't lose anything since it's a digital product I just created once and sell over and over again, and PayPal doesn't charge EXTRA for chargebacks.
EDIT: Just realized you said "I'd rather lose a sale than..", I read your comment to quickly. Yeah, I agree with you.
I'd like to be able to accept cards, but not if I get charged $25 if someone scams me. 2Checkout maybe? I don't know. If someone knows a card checkout that doesn't charge extra:
Let me know!
