Pretty good deal for these things. I have a pair and love them. Super easy to use with one hand. No button to hit, just squeeze and they automatically adjust and clamp down.
Price breakdown is 28.15+4.62 shipping =32.77EUR which translates to $36.60. Might be more or less, depending on where you are, this is to California.
Currently $46 on amazon.com right now, typically around $50.
NOTE: It says doesn't ship to USA, but I have no idea why it says that because they do. I just received some Knipex from amazon.de that said the same thing.
edit: They are $37.95 if you pay in USD, but if you have a card with no foreign currency charge, like Sapphire Reserve, you can pay in EUR and get a slightly better price.
