Thanks for the comprehensive response!
Not having access to G’s sales records I can’t offer an informed comment as to the popularity of the sample packets from a retail perspective. However, from a consumer’s perspective influenced by the Boy Scouts of America that ingrained in me a sense of perpetual preparedness, I would offer that not only is (in my humble opinion) the Go Juice and Grease the best, but that the sample packets are unique and offer a product delivery method unmatched in the market.
In summation, PLEASE consider offering the sample packets again. If nothing else, as a courtesy to consumers that have yet to realize how important it is to have a good supply of them!
