Teddy Books: Bundle Pricing Tinfoil?

Full disclosure, I enjoy the tin foil but don't usually dive too deep into it. Last night on the PPShow when the books dropped and the fellas were dissecting the pages looking for clues and whatnot someone (Michael IIRC) caught that the book bundle pricing didn't reflect what the advertised savings would be. For example: Teddy Books 1-5 Bundle was "Save 20%" and "Save Over 20%" ($49.99 instead of $64.95). Teddy Books 6-10 was "Save 23%" (same price, $49.99 instead of $64.95)

When you do the math, $49.99 is about 23% of the original price at $64.95. And lets excuse the "Save 20%" for a moment because the bundle does end up saying "Save Over 20%." So no big deal, I didn't think too much more of this last night.

Today when looking at the updated Teddy store site I notice the bundle pricing again and see that book bundle 1-5 is listed as "Save 20%"/"Save Over 20%", book bundle 6-10 is "Save 20%", and a new listing for all ten books has "Save 30%" advertised.

Again, not too concerned with the 5 book bundles because the consumer ends up saving more than the advertised sale price (saving 23% instead of 20%), but the 10 book collection you are not saving 30%! Quick math, $98.99 / $129.90 = 0.76, a 24% savings. So why are you saving less on this deal? Is it a mistake (that is what I usually would believe) or something else? I don't know. I liked that the numbers referenced in the savings are 20, 23, 24... important November days (exclusivity ends on the 20th, Thanksgiving on the 23rd, Black Friday on the 24th).
