IMHO you are way off.
Echo dot: was basically free newest gen alexa speaker, that anyone could do with all their accounts. If something is free or close to it, it automatically goes way up in the hotness scale. For example a $1000 tv can be $500 off, total price mistake but it still costs $500. OTOH a $30 item that costs $1 and is something many many people want, and it is highly likely to be honored that puts it way up there. and in this case deserved smoking hot.
Lowe's GC: It became smoking hot when it was clear that 1. People were winning $500 gc's from DDMS. 2. They stacked with each other and lowes had free shipping sitewide, so in essence it was around a $30 deal to get anything from lowe's $30 or under for free.
Google WiFi 3 pack: Are you kidding me with this one??? A $300 WiFI Mesh system for $30 and comes with 2 smart switches. I hope this was a joke. You could buy as many as you want and make or save huge money on this deal.
KidKraft Kitchen: Again a very popular item for $30 instead of $160, another reason that we have shifted to smoking hot on something like this, is people despise the word price mistake...
Google Fi: As everyone has already said, ridiculous to even suggest it. Once a deal is verified to work, and gets even better, can easily upgrade it from hot to smoking hot, not to mention brand new phones at this discout just doesn't happen.
ETA: Dan answered too lol.
I'm not saying these aren't wonderful amazing deals. I just think that there should be a high standard for SMOKING HOT! that some of these deals don't reach imo. Go back 2-3 years ago and I knew anytime that a SMOKING HOT! deal came across my phone that I needed to look asap. Now I look at my phone and see that I can get a free $5 GC at Lowes.
This is how I would've categorized everything:
Echo Dot: Hot! Hurry!
Lowe's GC: Here's a normal deal that we post, nothing (special) to see here. Yes I understand people won $500 GC. But ppl also won big on the marriott thing and that wasn't advertised as anything special on DDMS.
KidKraft Kitchen: Hot! Hurry!
Google Wifi: Hot! Hurry! BUT i guess i'm fine with smoking hot for $200 savings
Google Fi: SMOKING HOT! My only issue was going from Hot! to SMOKING HOT! for the $100 amex savings. Although I still think the deal was somewhat limited due to port-in issue and GC cash out.
