Our apologies, but we cannot provide support communications outside of our own systems, as it would be unmanageable for us to maintain contact with our Merchants if we had to check into each of their own, various preferred forums/wikis/etc. elsewhere. We are happy to provide support through this forum and via email; see our contact page here:
Please note that E-junkie is only a shopping-cart and digital-delivery service; we are not a payment processor like PayPal, so we cannot directly handle any actual payment transactions or funds. Our cart service simply hands-off order data to your choice of processor during checkout for payment arrangements to be made there, independently of our system. Once your payment processor informs us that an order payment has been completed at their end, then we would issue the buyer a thank-you email and any relevant key-codes or download links and optionally transmit the order data to a URL you specify where you would have your own means in place to do with that data whatever you wish.
I cannot respond to any issue in your earlier posts, but to address your more recent, particular questions in order:
A1: Consult PayPal's support staff regarding their transaction fees. We can support splitting micropayments/macropayments based on an order-total threshold, but we would have to set that up manually for your account here. Please send your micro/macro split requirements to us by email:
A2: Please see our help pages on customizing our cart screen here:
A3: I am not sure what you mean, but each of our Merchant accounts are standalone -- there is only one login possible for each account, and different Merchant accounts cannot be grouped into some association or interaction with each other, at least on our end. If PayPal has something on their end that requires no direct support nor special setup from us, well then that wouldn't concern us -- we just pass the order data off to them for payment, and what you or they do with payment funds from there is independent from us.
A4: You can sell whatever you are able to provide, but we would only handle taking the order and sending the order total to a payment processor like PayPal. Everything else, such as domain lookups, transfers, etc. would be up to you. You might find our 3rd party integration instructions useful to send order data to your own system for post-processing:
A5: We are not a payment processor, so we do not handle any payment funds and thus do not charge any per-transaction fees at our end. Our only fees are the flat-monthly subscription fee that you pay us automatically as a recurring payment from your PayPal account. The payment processor you choose to accept payments (presumably PayPal) would have their own fee structure, so you would need to contact them for info about their fees.
