@northerndiapers Maybe this might be an option.
There is a way around 'buying online' if you don't have a credit card and you live with others that don't know about your fetish. I used to have to hide my fetish from my wife as well which meant finding a way to buy online with out her knowing via the bank account and without a big package coming to the door. I now longer have to and sometimes she even engages with me in it but that's another story. I still get my diapers shipped to my flex delivery address (see below) cause that's what I'm used to. She probably wouldn't care if the package came to the house but like i said, that's just what i'm used to.
1. Buy a prepaid credit card 'gift card' from any drug store for whatever denomination you intend to spend.
2. Set up a flex delivery address with canada post here: https://www.canadapost.ca/cpc/en/personal/receiving/alternative-delivery/flexdelivery.page?ecid=murl|pdn|lh|297
It basically signs you up for a delivery address that you can use when making purchases online. the address is at whatever post office you pick where you want to pick up your package. It's like a P.O. box but free and accepts pretty much any size parcel. I've gotten some big ones there before loaded up with diapers, boosters, clothing and etc. Good times. You can pick up whenever you want (you have 15 days before they return to sender) and transport to your stash spot when it's convenient for you
3. I'm not affiliated with these guys/gals in anyway but I strongly recommend shopping here at Rearz.ca https://rearz.ca They are canadian, out of ontario, and ship quickly and discreetly. That last one of course is a must.
Some of my personal favorites are the inspire+incontrol nighttime briefs https://rearz.ca/inspire-incontrol-nighttime-briefs/. White plastic backed diaper that hold an insane amount.
The rearz safari nighttime briefs are great if you're into printed diapers https://rearz.ca/safari-nighttime-briefs/ incredibly thick and also holds an insane amount.
I'm currently wearing my new favorite right now as i'm typing. Little rascals nappies https://rearz.ca/little-rascals/ thick, cool print, hold a ton.
Anyways, I used to lament about not being able to buy sweet diapers online until someone else pointed out to me the flex delivery option and it was an absolute godsend. Hopefully you can make use of it too.
Cheers,
