I crossed at Buffalo as well in the beginning of Dec. It was around 2:30pm on a Sunday, and there was NOBODY ahead of us. I think everyone was still shopping, we saw the big tour buses at the Galleria. I spent well over $500, but had claimed only $500, and had receipts ready in an envelope. Since this was a 48 hour trip, I wasn't over by too much, but still got sent to the building to pay taxes. One tip, don't just hand over your receipts, don't even have them in your hand, wait to be asked for them. Chances are they won't ask. I was asked if any of the merchandise was kids clothes(which alot was), and I had to pay less than $10 in taxes in total. A little inconvenient, but there was no line in the building.
