That seems like a helluva lot of work for such a small purchase (no pun intended). I live near and work out of border town Niagara Falls, ON. Would not even occur to me to put the time and effort into driving around town. However, each their own - all the power to you if you can make the effort worth while. The brokerage fees typically do not outweigh the cost of my fuel and time.
That said, this is EXACTLY why I avoid vendors like the plague that ship with UPS exclusively. Here's why: I once won an eBay auction for some custom floor mats, costing me $0.25+S&H. The seller declared the item for the full retail value and UPS charge me $50.00 brokerage before they would hand over the parcel. Would have personally declined the shipment, but a family member accepted the package on my behalf and paid cash out of pocket. Lesson learned!
