I have never ordered from them as I found them overpriced.
I also live near the US border so I just ordered from US sellers and had them shipped to a parcel depot stateside and brought them over the boarder myself.
If you are looking for a good Canadian seller agecomfort.com has a good selection of adult diapers including rearz diapers, with free shipping on orders over $50. Just make sure you tell them to not add you to a mailing list as they will send you a flyer about twice a year.
Also rearz.ca is a good website to order from with free shipping on orders over $120
