All SMI customers can give recommendations and receive a free silver coin as a token of our gratitude! To qualify, you need to have a user account and provide 4 unique customer recommendations that are realised through any purchase whatsoever from the SMI e-store. Recommendations are given via a unique recommendation link visible when you log into your account. If a purchase is realised, SMI will give the recommender a valuable 1-ounce Canadian Maple Leaf silver coin! This bonus is valid for every 4 subsequent recommendations.
