No offense taken! The short answer is that it won't be right for every customer. Some people just want to bundle everything together. Some are looking for the best price no matter what.
We felt that we had enough people asking for a Velcro-type solution, that it'd be worth offering the best version we could find. For those that value the convenience of getting everything at once, Dual Lock is there for you. If you'd like to get your deadener from Second Skin and adhesives from Amazon, we're all for that too.
