Why use Paydotcom for affiliate programs?
Free sign up for affiliates - It's to affiliate management companies advantage to have free sign up for affiliates since they receive a small percentage of each sale, which is how they make their money.
Free sign up for vendors - The free vendor sign up is for the first product. After that, there's a ridiculously low lifetime fee to submit an UNLIMITED number of products. Affiliates may sign up to sell as many products as they wish.
Individual sales or landing pages - completely separate sales page WITH the same account. Now my affiliates may select product which only go with the theme if their website if they have one.
Individual commissions per product - Different commissions can be setup per individual product.
Products can be linked - The merchant has the option of linking all or some of his/her products together. Thus ensuring affiliates are paid for upgrades during sales and even after the original product is purchased by the customer. I personally have linked ALL my products. I'd rather err on the side of my affiliate.
Recurring payments -Affiliates are paid for subscription services
Immediate payment through Paypal - For security, Clickbank makes vendors wait until five credit cards have been used before mailing a check. Paydotcom vendors receive immediate payment. Now vendors may withhold payment for affiliates up to 30 days depending on their return policy.
Return policy up to the vendors - One of Clickbank merchants' huge complaints is Clickbank's borderline insane customer blinks wrong return policy. Paypal will negotiate with complaints but they seem to understand both parties have rights. Since Paydotcom only manages the affiliate program, they have nothing to do with any negotiations.
Physical products can be sold through PDC! - That's correct. You're not limited to digital products, though they continue to be the most popular due to ease of delivery and instant gratification of customers. CDs to clothing may be sold through Paydotcom.
