Terapeak showing inaccurate shipping?

[little.luxe.armoire]

Has anyone else noticed that Terapeak is way (sometimes way, way) off on both sold and active listings?

As an example:

From the top, the shipping shown on Terapeak for these three active listings is $5.41, $6.66, and $100 - when in actuality, the shipping shown when you click through to the listings is $5.65, $6.95, and $5.70! There doesn't seem to be any rhyme or reason to it. The sold listings are having the same issue, which makes it somewhat questionable for price comparisons.

I only noticed this today, so I'm not sure if it's a new bug or if I just didn't realize it till now. The $100 shipping jumped out at me as so egregious that I had to look at the listing and that's when the problem became clear.

I found the item. Active listings, not sold listings, so shipping shown will not be exact since no payments were made yet.

Listing 1: 394506133424

Charging for an 8 oz FC package ranging from $5.40 - $5.85 so the $5.41 shown is within a couple cents of the low end.

Listing 2: 275637553247

Charging for a 12 oz FC package with a 50 cent handling fee ranging from $6.65 - $7.15 so the $6.66 shown is within a couple cents of the low end.

Listing 3: 134432285289

Charging for an 8 oz FC package ranging from $5.40 - $5.85. Initially I thought the $100 might be because the listing offers international shipping, however the international rates are mostly in the $30 range so I don't know where that $100 is coming from.
