It is recommended to use PayPal Goods and Services when paying for an item. There are no buyer protections when sending PayPal Friends and Family, Zelle, Google Pay, Venmo, CashApp, Crypto, among others.
Still have 50 secondary $1000s and 100 primary $500s. Preference initially given to those interested in buying all of one denomination. If there are no takers after a couple days I'll consider splitting them for smaller amounts on a first-come basis.
