Can we get sales tax to be included in the price on the shelf? The main reason I don't use cash is because I have having change, and sales tax always ends up with me having odd change. In Oregon, I use cash a lot more often because prices tend to avoid weird change. Some restaurants include tax on the shelf price ($3 for hotdog instead of $2.99 + tax or whatever), and if that were more common, I might forgo credit/debit cards.
