Matty Collector started charging me sales tax in summer 2012 and I live in Ohio. No other online website, other than those that have a physical location in my state (ie - Walmart, Target, TRU), charge me sales tax today - not even Amazon. It really sucks because it's an additional 7% and they include the item's price PLUS shipping in their tax base.
I obviously wish they didn't collect the sales tax, but by law we are required to self report online purchases that did not collect sales tax on our personal income tax returns each year. I think most people don't do that because it hasn't been, and probably can't be, enforced by the IRS. That is why they are pushing for all online retailers to collect sales tax for online purchases.
