Sound deadening, Carpet, and floor pan repair questions

Interesting, noticed the Noico and Kilmat websites are nearly identical. After some poking around in their terms and conditions, they're both companies that belong to STP Atlantic LLC.

Kilmat is $1.65/sq. ft and Noico is $1.77/sq. ft according to their identical descriptions of the same material in the same quantity. So probably kilmat it is, since they're identical products produced by the same company. Strange they would sell them at different rates, and kilmate advertises shopping around on their landing page, so they probably operate other, even more budget friendly, sound deadening companies if i had to guess.
