Looking for Deals

Looking at Prime Deals today makes me think of looking through flyers for XSCargo over 15 years ago. I had been looking for marked down items that I could potentially resell on eBay. There never was a good deal.
Now, I look at Prime Day and kind of shrug… I have to go through heavy cognitive load of assessing whether I need something, if the sale is good or not, and whether I now need to adjust a budget to get it.
Yes, if I were in the market for a particular product like a TV, now might be a good time to check them out. But I’m not. Should I get an older generation Braava vs a used new generation Braava?
Sometimes it’s better to let the deals come to you.
