I use it for Groupon, Netflix and odd online shopping. I used to use paypal for eBay but the ebay mobile app looks dated and I can't see any feedback for the product. I prefer Aliexpress.
I use PayPal when buying from small unsophisticated-looking mom and pop ecommerce sites that I don’t trust to have integrated credit card payments in a reasonably secure manner.
I don’t. Only ever used it once when my previous employer was using them and I had to have one so I could try out our product. Deleted the account as soon as that job ended.
