How to sell stored codes (like phone cards) and generated codes (like software registration codes)?
Using E-junkie to sell stored codes (like phone cards, discount coupons etc.)
While adding or editing your product in E-junkie Admin, you can check Stored Codes checkbox and click the Submit or Next button. Then you will be able to enter a list of codes in the PIN/Registration Codes field. Whatever you put on each line of text will be considered ONE code; if your one-line codes are long enough to "soft-wrap" onto additional lines, only a manual "hard return" would count as the end-of-line that divides each code in the list. You can have a list of up to 10,000 codes stored at any one time.
For however many units the buyer orders, that number of lines will be removed from the list and emailed to the buyer. You can also customize your thank you page to display these codes to the buyer.
When your list is down to the last 5 codes remaining, we send you a notification, so you can restock your list before it's depleted. Buyers would be unable to order a Send Stored Codes product if there are no codes remaining in the list. When you restock your list of codes, the new codes do not take effect until you click Submit to save changes, so buyers ordering before that point would receive a code from whatever remains of the old list.
TIP: The Random.org string generator is pretty good if you need a way to manually generate a list of random codes for this Send Stored Codes method.
