I just purchased aMember v4 to upgrade from v3 and found that it has no multicards.com payment plugin while it was there in v3. I asked amember helpdesk but they did not help. Can any one develop multicards payment plugin for amember v4? OR Suggest a payment plugin that is similar to multicards, so that I can use it as template. Multicards payment system is non-recurring, no fixed products, no fixed cost for products. Just send any product name, cost, buyer's contact information and it posts IPN results after successful payment.
