Try it and report back.
For me 1-2 day delivery is 1 day, 2-5 is closer 5-7 business days
If you can order before their shipping cutoff time (don't know when that is), my guess is you would get your package Tuesday.
This is an order I placed at 3pm on a Friday and got it on a Wednesday.
I emailed them telling them it came too late (I needed it Tuesday) and they told me 1-2 from Friday is Wednesday.
Side point I ordered chocolate and most of the bars were white like they weren't stored well or just plain old.
CS as of now basically just said too bad...
