I don't want to waste to much of your time, because i know that some people can't be bothered reading like 6 paragraphs of useful information so i'll just jump right in.
Nurtured family have a huge array of products for babies and mom's. They specialize in diapers and one of the most cost effective and environmentally friendly way to diaper your child are fuzzi bunz. They are designed to be trim, keep your baby's bottom dry, allow varying levels of absorbency for daytime vs. nighttime, and to clean up beautifully with minimal effort. I have 3 kids of my own who can be a real handful at times.
For my children i go with the fuzzi bunz brand (there are plenty of other brands to choose from) simply because they are the most cost effective and get the job done basically. Nurtured family also specialize in nursing and maternity, baby clothing, toys and a whole lot more. When ever we need something for the children my wife always go's to nurtured boutique simply because you really won't find any place cheaper or with higher value. And i'm talking from experience here.
Now there are plenty of online stores to suit the needs of you and your baby, but i don't think (personnel experience)that there is a more cost effective and value for money store than nurtured family. You can go ahead and browse around the site to decide for yourself if it matches the needs for you and your baby.
