Yep - depending on where you live, there can be a benefit to having something delivered rather than taking delivery at a brick-and-mortar store. Especially with big-ticket items. 

Example: A few years ago, I bought an ATV in Littleton. Taxable amount was about $10k. Sales tax at that location would have been $725. Sales tax at my house (unincorporated Douglas County) is 4.0%. The dealer would deliver the ATV to my driveway for $100. Net savings of $225, just for waiting a couple of hours.
