Sorry about the trauma of losing your kit.
I have bought quite a few cameras from Canon Refurbished site (I never transcended to SLR/mirrorless). Occasionally, there will be extra discounts to sweeten the deal.
Also, there might be a very slim chance that your trip insurance or homeowner/renter policy might help ease the sting of your loss.
Costco is fine.
I have alternated between Costco and TireRack over the last few cars, mostly depending on my mood of the day.
For “my” car, I like to read the reviews and choose online at TR, and have them shipped to my mechanic for install.
For the others, an instant rebate sale at Costco on a set of Michelins is a no-brainer.
Edit to add: I misread “price” as “place” so the above is not “the answer” to your question.
I did briefly poke discount tire with the Yokohama tire from your list, and the cost is essentially same as your quote - just north of $1K without their extra warranty.
