Meaning of a sentence

Seriously, I have reservation about the English level of the person who drew this agreement. If anyone can understand this statement, please tell me what that means. I don't have a clue what it said.

Anonymous"In case of a complex offer of prices there is no obligation for delivery of a part of the order for a corresponding part for the price stated for the entire order."

To me it says, "We are not obligated to prorate partial orders". In other words, if they quote you the price as a dollar apiece for an order of 1000, thus costing $1000, you can't expect

I think it's pretty well written, except that the expression "complex offer of prices" is not immediately obvious, and makes one think a bit. Perhaps the expression is common in a country other than the US.
CJ's reading is the way I would take it.

Edit. Well, I guess "complex offer of prices" is okay once you get used to it.

"In case of a complex offer of prices there is no obligation for delivery of a part of the order for a corresponding part for the price stated for the entire order

To me, I have problem relating to the highlighted texts. I think this is a badly written statement because there are too many "ofs" and "fors" which cloud the clarity of the meaning. I believe also a comma is missing.

Yeah, you're right. It could be improved by using two sentences. (It was probably written by the legal department.)
