If you are buying in bulk, you can calculate the amount and pay through PayPal
here (https://paypal.me/callontime) and add a note to us about how many and which calling card you are paying for. For
example, if you want to buy 100 (QTY) of $5-Africa X Calling Card's PINs, pay $500 and add a note
at the note section as: For 100 X $5-Africa X Calling Card's PINs.
