is going to be taxed at 15.5%. Shipping is expensive (up to $60/case...$5/bottle). I don't see this changing much, though a few will try. With the turmoil in the wine industry today (less sold and high costs... and too much expansion in the last 10 years). The only real value wines are from outside the US, and they don't ship directly to you.
Just don't see a win/win in this move.
I don't know off hand, but I suspect that 15.5% is not going to be more than the combined sales tax at the package store, the wholesale tax on wine in Mississippi, and the markup the ABC warehouse puts on it?
ETA: Very brief internet search indicates ABC marks up wine 27.5%, plus you have a $0.35 per gallon excise tax, then you have the 7% sales tax at the store.
Ignoring the excise tax and assuming you pay a 33% market up at the local package store or for buying direct, for a bottle that ABC buys for $15, you will pay $27.22. If you buy direct and pay a 33% markup on the wholesale price from the distributor, even with a $5 adder for the shipping, you end up paying $27.94.
Have no clue how realistic the 33% markup is (I just pulled that from an internet search), but if that is roughly correct it looks like it will be cost competitive for moderately priced bottles of wine.
