Dilemma solved !!

I did hear back from Summit - saying that there would be no additional charges upon delivery of my order (roughly $400 Can. in value). Canadian sale taxes were charged at the source. Free shipping.

I ordered the item on Monday, did not pay for any upgraded shipping. The item arrived today. No additional charges.

So here was my thinking process ...
If I'd ordered it shipped to U.S. Address I would have paid N.Y. sales tax. U.S. Address would have charged $5 to receive the package. Then when I brought it home I "might" have been charged Canadian sales tax at the border. Add the time and expense to drive down and pick it up. Pretty much a no-brainer!

However, I do have a bunch of stuff coming from Stephens, YearOne and RockAuto - none of which provide free shipping so these justify U.S. delivery and the drive to pick up - on the way to Fall Carlisle.
