I was using the "Buy" button instead of the one which should be used for donating. I noticed that from donated 3.5 dollars they kept 0.5. Does anything similar happen when I use the "Donate" button or not?
Could you please tell me how much will they charge me? But the fee still should be lower than the other one (when I buy something), right?
the paypal fee can refer to https://cms.paypal.com/us/cgi-bin/marketingweb?cmd=_render-content&content_ID=merchant/merchant_fees
