Sure SFI wants their money...but I'd raise suspicions about any company that produced a bogus safety certification sticker of any sort. If they are willing to lie about the authenticity of the safety certification sticker then what else are they willing to lie about? Bad business practices all around...if the cert is that expensive I'd look for ways to reduce manufacturing costs and/or explain to the customer how much the cost of their product goes towards that SFI safety cert, so when they raise their prices to cover the additional $$ SFI wants the customer can raise their ire at SFI, not Impact.
