What was this person trying to tell me or ask me?

I get a phone call. Some foreign sounding guy is identifying himself as an “amazon affiliate company”, asking me about an item on Amazon that I sell, (in his words – “cross-sell”)? Ok, what about it? He mentions the manufacturer name, and (I think) he thinks I am the manufacturer (big company). I say, I am an authorized seller I am not the manufacturer. So he just goes babbling on about how he understands and more babbling about cross selling. Never did figure out if he has a problem with the item or me or the manufacturer or if he just wanted to sell them. Anybody else get weird calls about “cross selling”?
