In the long run your affiliates often become the best customers. Many affiliate programs are now requiring their affiliates to purchase the product in order to become a re-seller. I believe this is part of a trend in Internet marketing. Product owners are more knowledgeable as to the value of the product and what it can do for the prospective customer. Using hype or unreasonable claims is to no-ones advantage.
Unrealistic claims bring out the greed in others and ultimately disappoint everyone.
Slow Response Or To Inquiries - No Guarantee Consider every inquiry a selling opportunity. A quick response builds credibility because you are demonstrating your willingness to make yourself available. An airtight guarantee often makes the difference between earning a lifetime customer and losing a sale.
