Many of our customers buy 3 packs of Streptokill in order to take advantage of our buy-2-get-1-free promotion. This promotion is also covered by the guarantee of "100% effective or free", but please note that only 1 of the 3 returned packs, should you return them, may be unsealed or partially-used. The other Streptokills must be unsealed; the 100% money-back guarantee applies to no more than one unsealed pack.
From our experience, Streptokill helps the vast majority of people and fewer than 1% of our customers have use the return-policy guarantee. We firmly believe that you will join the 99% of patients for whom Streptokill yielded significant results, and we look forward to having you among our satisfied customers.
