Going to chime in here..

I am a big paypal user, and have been using it about 10 years now.. love love love them..
Here is the deal...
1. sending friends and family for a purchase is against paypal TOS as well. While you CAN do it.. if you get caught sending, its not a good end result for you or the buyer.
2. sending friends and family as stated earlier in the post.. voids the buyers protection. you have NO recourse in getting the money back.
3. The fees are not HUGE, though when sending a larger amount, (ex $200+) it does start to eat at the sellers received amount. There are some stores out there, that pass the CC fees to the customer, its normally only when a transaction is under $10. Its kind of tacky to tell a customer that is spending $300 with you, that they need to cough up more money. I know buyers don't like it even if its included in the price, but this happens so much with many many places that take paypal.. you just don't know it because they include that minimal fee in with the price already. Its common business practice...sadly.
Now, here is what I do.. and NO ONE asks me to do it... its just how I am... If I purchase something for $200, I will send $210... (I usually just do $5 per every $100)... In the case where I am sent an invoice for $200.. it does not give me the option to add funds, so that gets paid as it is...
Most of the time when I do this, its with people that I know, people I might be picking up an animal or product from in a week, (I will go and pay them now incase they really needed it NOW and not in a week) AND people Im making a LARGE purchase with and making payments. Each time I send a payment, I add a bit to cover fees. Usually as a way of saying thank you for waiting a week for pick up, or allowing me to make payments. It also shows them I am serious about the item I am purchasing.
I am NOT in any way saying everyone should do this... it is just how I am.
Its not unheard of for businesses of any type to charge a fee for CC use (gas stations do it a lot).. EX: 2.39 per gallon cash, 2.49 per gallon credit/debit.
To me, its not so much who pays the fees as much as it is about its presentation... you never know what you are paying for when you purchase from some people... You might have purchased an animal in the past that was $200 and in all reality, they could have already included any fees or packing fees in that 200. No one will complain about that because you just don't know... doesn't make the seller bad.. it just means they are projecting any costs and adding it to the retail price of the pet.. much like some include taxes in items so they don't have to figure it out to charge on the spot. Which btw, I am pretty sure (not 100% though) you have to pay taxes on any animal purchased in a store? Which is an added cost that no one complains about... would you still feel the same if a breeder said, ok the animal is $200 PLUS tax? Most places include it in the price unless you go to a pet store to purchase. That or they avoid the IRS...
