Could you explain the meaning of a sentence from buisiness mail I've got a business mail from my correspondent. But I can't fully understand the meaning of one of sentences from the mail. Below is the sentence: We(B company) have advised the "A company" only of our initial conversations with no deliverable time frame currently should they preference your product. I understand that B company has talked A company with no precise time table. What I can't understand is the rest part of the sentence. "should they preference your product" Dose it mean "If they give preference your product" Understanding the meaning of business English is totally different from daily conversation. It's really hard to me.
