The cheapest and easiest way to get Indiegala bundles is with a subscription. As a subscriber, you will be guaranteed a slot to all the Indiegala bundles I host.
I also recommend paying in bulk to minimise PayPal fees. You may pay in advance, or I can also send you weekly/fortnightly invoices and you'll receive your bundles upon payment.

Contact me if you are interested in a spot or have any questions. By now I'm quite familiar with how both Indiegala and PayPal works, so feel free to ask anything :)
