Did I make a horrible mistake??

3. Anything physically or budgetarily large, if I start to really 2nd guess myself while in the cancellation window

I cancel. You can always re-order once you REALLY feel you've done your due diligence. And I do a LOT of that before I buy anything expensive that I'm expecting to last a long time.

And big things I really try to buy local, and optimally from Costco. Returning large items is a hassle. Also to me, patio furniture is wildly overpriced for what it actually is, the vast majority of the time. If I were furnishing a patio I'd be all over craigslist, fb marketplace, OfferUp, etc. I like buying gently used stuff. But that's just me. Good luck either way, if you get it, I hope you love it

I do like the set though, you have good taste
