The big boys started it but it had filtered down to even SPs.
My shop is tiny and we do SBT for new product.
You do have a point about alcohol laws but in every state I know of in the Midwest (and yes we did do business in Indiana) SBT was allowed.
Texas has traditionally been very restrictive with alcohol sales. Religious opposition to drinking + big business alcohol manufacturers and distributors support for restrictive rules that give them quasi monopolies by raising significant barriers to entry by new, would be, competitors.
