What about tax?

Each state seems to have its own laws regarding how to tax items in relationship to coupon use.  Here are the differences:

• Some states require you to pay the tax on the full value of the item, even if you used coupons to get it for free.  
• Some states require you to pay only tax on the "after coupon" value...so if you got it for free, then there will be no tax required.
• Some states do not require tax on grocery items, so those items will not be taxed regardless of your coupon value.  More than likely, you will still pay full tax on any "free" items that are not grocery items in these states.
