How do I send payment using Google Pay? 1). Download the Google Pay App on Android or iOS. This payment option only works for United States based accounts. 2). If the seller has listed their item for sale for $100, you pay only $100 (we charge no fees). Enter [email protected] for the e-mail address and your playerup username in the Memo. Then click Send. 3). Once your payment has been completed, open a ticket with Middleman to start your order, and provide the URL of the item you purchased / sellers username. .
