Please help with this sentence?

Question:

I'm ordering at www.bk1.jp and this is what is says when it offers to enter the BK1 point club:

What does it mean? Does it mean 1% from my order total sum or 1% of what? And where does it go?

Please see the sentence below.

Answer:

The orders received in this sales campaign are not applicable for a 1% top up on bk1 points.

i assume there is some bonus points that are given in an ordinary purchase.
