https://www.springer.com/gp/shop/yellow-sale, warning, the site is REAL fucking slow, if a page doesn't load at once you have to reload it like 5-6 times at least

so Springer's having this sale and i'm wondering what i should get. inb4
>what do you need them for, there's libgen
i like physical books
i already have Marcus' Number Fields, which i'll self-study over the holidays. the books i'm considering are the following:
An Introduction to Manifolds by Tu (want to learn manifolds, differential forms and Stokes' theorem)
Algebraic Combinatorics by Stanley (i know very little fo combinatorics/graph theory, but like linear/abstract algebra, and this looks like a very cool application of the latter's ideas to the former)
Ideals, Varieties and Algorithms by Cox et al (it's a very large book, so this would be a very cost-effective pick-up, as the book's half-price right now + i wouldn't mind learning about Groebner bases)
Algebraic Number Theory by Jarvis (i've already got Marcus, but this has really good reviews on MAA and i'm wondering whether Marcus is too high level for me anyway)
Real Mathematical Analysis by Pugh (i wouldn't be really learning all that much from it, but just to have as a desk reference)
A Fixed-Point Farrago by Shapiro (curious about fixed-point theorems, but it's kind of pricey, probably won't get)
