Absolutely Pirl.
I heard of a method to determine if the plant is rooted well enough at the nursery. I give a gentle squeeze and if the pot seems to give a lot it means there arent enough roots to purchase.
I also check the stem and gently tug it,if the plant gives it means it is a new plug.
Also, many nurseries stick plugs in pots and mark them down for end of season sales.
This means the customer is getting a newly plugged pot with a high probability of decline over winter.
Of course this test method isnt possible with online ordering but shopper beware of sales.
