Wrong diapers :-/ rant

Brittany • Mommy to a wonderful 12yr old boy, 9yr old boy 7yr old girl 6yr old girl and 3yr old girl. Due March 11th 2023 with a boy.
I plan on cloth diapering but I'm not going to start that until 3mth. So for now I plan on using organic chlorine free plant based diapers. I can't buy them in a store near me so I order them off the internet. I ordered 4 boxes of 36newborn seventh generation diapers from SAMs club and got them in the mail today and they sent me 4T-5T training pants instead. How do you mix that up?!?! I'm so irritated and now don't want to try that again I was saving 4-6cents a diaper buying them that way and it was free shipping toys r us doesn't offer free shipping unless you spend a certain amount of money. Gerrr.... Would anyone risk ordering from them again? I have 1-3 weeks till baby's here. I kinda need diapers.
