Right now in store at Target they have the nest cam for $199.99. You can price match it to their website target.com for $139. Link below.
Then at check out, use the CartWheel or Target app to add the 30% off coupon for nest cam. That will bring the final price down to about $97 plus tax. The cartwheel coupon ends today.
If you want to be more careful, add filler items such as grocery when checking out. Just so the associate doesnt notice it. That's what I did.
