Q for ppl who know delivery things. I ordered something online today (Sat) and I picked next day delivery cause I thought maybe it'd come on Monday.

BUt now i'm thinking cause it's the weekend, will I still get it on Mondays, or will the order process on the next business day (Mon) making the next day delivery day Tuesday?
I'm confused. I've never ordered next day delivery before.
why am I worrying about a days difference. smh. I guess I am curious though ahhaah.
