I seem to remember you having a different attitude toward my Maryland purchases the last time we were both involved in a discussion on this topic.
The law is the law, and I’ve known the law for years, so I don’t know why you would remember me saying anything different. The standard Sales Tax in Maryland is 6%, which is less than Virginia.
There are some food items in Maryland that are not taxed; if you buy those and bring them home, then you would have to file use tax for those items, if they are taxed in Virginia (which taxes food, but at a lower rate than other items).
But this applies to a small set of Maryland food; items sold by a “food seller” that are meant to be consumed off-site, but are not “prepared foods”; the chances of you buying such things in any quantity, and then bringing them home with you before consuming them, are rather low; the chances of the store taxing you properly for them is probably lower. And the amount you’d owe would be so low as to be in the noise.
