While granted I am still very new to this but I noticed with the mini cooper poly it was a $99 buy for the free poly but I figured it was because the mini was $99. I just looked at September's add and the spaceman poly is also only free with a $99 purchase. If this is the new norm will polys go up in value because fewer will get them free, even though most decent sets at LEGO Shop at Home are $99+ now. Or is this normal for Lego?

if i remember correctly , chima the current promotion is for $50+

$99 is most common, I think, but $50 and $75 are also used. I'm not sure of TLG's system of choosing the thresh hold, but the costs do vary.

High-end or "in-demand" products, it's not too unusual for them to use a higher end buy-in for the freebie.

Still not bad compared to other countries.  I think the Aussie folks said they had to spend like $400 for free shipping. 

 

With a standard poly like the mini and VIP, it's still going to get you 10-20% off in the end.

$50 is actually fairly common or at least it used to be. I think all these large exclusives may be influencing the limits being set for earning these promotional polybags lately.

Come to think of it, Benny's Spaceship is $100 which recently became available and both are Classic Space related. Just something to ponder upon.
