Uh these are $1.99 for 3 on chewy.com.
Your link didn’t take me to the balls
LET ME SEE THE BALLS
LINKS TO BALLS OR GTFO!
So, while it’s $2.99 now, even if we were to pretend that they were still $1.99, you’d still have to factor in shipping costs there…
Okay. Shipping shows up as $4.95 flat rate. So I guess that this would have been a good deal on Woot for Prime members.
I think. I don’t have my Animaniacs calculator with me.
The Woot! deal is for the extra small size which is $1.99. I’m not sure why it defaults to the small size although I choose extra small.
I stand corrected.
My point still stands though.
I buy dog food there. I hit $49 quickly for free shipping. Anyway, the point is that it’s good to check prices.
Of course, though for some people, results are different. 
(Actually, this kind of reminds me of when I built a LEGO Bugdroid by buying individual pieces online. Sometimes it was better to pay more for a piece because then I could combine purchases and save on shipping. After all, I’d rather pay another 5 cents for one piece so as to save 4 dollars for postage.)
