Sales tax is a small part of it, but most item&#x27;s just cost less period. When you declare at the border, as long as you don&#x27;t have more than a few hundred dollars, you&#x27;re typically alright. I&#x27;ve declared up to $350 worth of groceries and they let me go through no problem. Liquor&#x2F;Tobacco is a different story, however, once again, I&#x27;ve crossed and declared a flat of beer (24) and was asked to pay.
