Is it too *early* to buy pies?

I'm assuming you meant "early" in the title, not "easy"... .Although I was prepared to answer the "easy" question, thinking maybe you meant "are we getting lazy because it's too easy to buy a good pie". I was going to reply "thank goodness for pre-made pies!" hahahahaha

Anyway... as for being too early, if you could fit a Costco pie in your refrigerator I'd think it would be okay. It won't fit in ours though so I'm heading there first thing Wednesday morning.   I plan to pull into the parking lot half an hour before they open. I'll get my favorite spot (the one that points directly to the exit, lol) and read a book until they open. Then I'll go straight to the pies, get what I want, grab anything else that I've thought of (which won't be much), then go directly to the self-checkout. I'll be back to my car and out of the lot in 20 minutes.

I’m sure it will be ok - but I would wait until Tuesday. Or buy a premed crust and make it yourself Wednesday- pumpkin pie is the easiest! (but I totally get it if you don’t want to lol)

We've purchased Costco pies on the Sunday before Thanksgiving and they've been fine. As mentioned above, refrigerate them to make them last. We are having a small Thanksgiving this year, so I picked up two small pies yesterday. I put them in the freezer. We'll see how that goes!

Absolutely. I had no problem getting one on the Tuesday before Thanksgiving last year. I'm counting on that this year! 

if you're concerned, you can freeze shop-bought pies - I didn't realise that until last year when I was looking at pies about a week or so before Christmas and the bakery guy who was stocking them suggested that if I wanted them, I should buy now and freeze because they expected to run out (and when I went back closer to Christmas- he had been right). They tasted fine defrosted (mine were from Publix - pumpkin, pecan, and apple)

It would definitely be too early to buy a pumpkin pie in my house.  By Thanksgiving, there would be nothing left but crumbs!  I love pumpkin pie and could easily eat a piece every single day. 

I was going to suggest freezing it too. Pumpkin pie freezes very well. One of my brothers grows pumpkins in his yard and then makes about a half dozen pies and freezes them to thaw out and have later.

I’m baking ours on Wednesday.

I'm sure Costco includes a date on it. I've often been amazed at how long store bought pies last even at room temperature, so you really can't compare to how long a homemade pie will sit out.
