Can the eBay shipping calculator be relied on for UPS quotes?

I just listed a large item. In AW, I used Calculated Shipping in Shipping Options; Custom Weight of 65 pounds; Very Large Package (Oversize 2 -- it will be about 30" x 32" x 36"); Packing/Handling of $10.00; and I selected only UPS Ground.

When I go to the auction page and plug in a New York zip (10025, with the "home" zip being 92130), I get a very reasonable $80.40 (please check and see if you get the same figure -- auction ID is 140111652084). But when I enter all the same info at the UPS web site, I get $194.60. What gives?

I'm going to have to remove the shipping info or risk under-collecting.

Any ideas?

Thanks, Sue
