What Am I Missing?

I receive lots of email advertisements and promos from companies I've ordered from in the past. 

But this one struck me as rather odd.  I can envision someone wanting to buy this guitar, or even this fake Christmas tree.  But why would anyone buying this particular guitar, buy it because they would also get a free fake Christmas tree?

What am I missing here?

Both are likely to be used for a month then never seen or heard from again?

That's funny. I'm going to share that one on Facebook.

Backward masking subliminal advertising so you can pretend you are in the "Trans-Siberian Orchestra."

Maybe they have you confused with a pastor who welcomes electric guitars and Christmas trees in worship service.

I guess Rockin' around the Christmas Tree is too obvious?
