Originally posted by bigdavephoto 100% true here in the US. Here though is the thing most people don't know. If you use a credit card at the store to pay for what you are buying, the store gets charged a fee by the company that owns the credit card machine you put your card in.
That is the same idea that paypal is set on. The seller pays the fee to use the service. It is up to the seller to decide if he/she eats the fee or pass some or all of the fee onto the buyer.
But there is a big difference in the scenarios we are discussing.
If a seller is selling online and using PayPal as their settlement service they know they will be hit for those fees at the time when they are pricing the goods. They should add the fees so they clear the amount they want to clear. And if they object to the PayPal fee either choose a different settlement service, get out the business, or print receipts with the PayPal fee itemised in huge print with rude words about the exploitiveness of PayPal.
If a seller is selling to a f2f customer other methods of payment are available, such a government issued legal tender, where the fees do not apply. In this case it is not unreasonable to have a 'cash price' and a surcharge for using a card, so long as the surcharge is clear tot he buyer BEFORE the transaction happens, so a buyer can make an informed choice about cash or card.
