That's not how it will work.
If they cut deep into margins and price out other retailers, it will be a slow bleed. Start with maybe 10% of assortment and keep scaling. There will not be enough buzz to make any effect in the industry if they execute this strategy.
It's my most executed guess This is not a data play, This is purchase the largest homebrewing company, use their immense buying power & capital to lower prices, price out other retailers, start whole distribution. Then once they have even more dominant market share and a distribution network in place, raise prices.
It's what happens, very common MO. Standard Oil did it and that's why finally broke up their monopoly. Undercut prices in certain areas to kill business, then swoop up assets and raise prices.
