It looks like PayPal fees will be a pain. If you want to weekly pay with paypal, then that is fine. If you want to limit your transactions and buy in bulk to prevent fees, then I will allow it.
I am not offering a "package." However, if you want to send $25 through paypal, then I'll mark you down for 5 sheets. Just email me the weeks that you want access. I do not want to keep a ledger, but the fees will add up for some users, so it's an option that I will make available. However, I will cap the amount that I accept. I have no clue what that number should be, so I am going to write down $50. You're welcome to convince me otherwise.
I apologize for any inconveniences, I am new to the business side of this. I am going to set up a Venmo account. With Venmo, if you pay with your Venmo balance, your linked bank account or debit card, then Venmo waives the fees (only credit card transactions trigger fees). Transfering Venmo funds back to your bank account or debit card is only a 1% fee.
