I think it's been at least 10 years. Technically you're supposed to pay your own state sales tax any time you buy something away. I regularly escape IL and go to WI for many purchases as the tax here is close to 10%. WI half that. So many times Fleet Farm or Farm & Fleet in WI will get my $$$. When I bought our Inverter Generator for power backup. I discovered Northern Tool in Madison sold the same one Hazard Fraught does except theirs is blue, carried a longer warranty and cost about $75 less. Between all those things plus the HUGE saving in sales taxes a few $$$ worth of gas (which I also bought in WI
) was more than worth it.
