I've just started dealing with Mothercare, they match the prices of all the other baby shops within 25kms of their stores. Also they have a rewards program, so when i bought my car seat I was rewarded with $15 towards future purchases. I wish i had found them sooner. The women at the store were really nice to deal with to.
I shop at pram warehouse but their stores are a mess! They really need to learn to display better, and bargain bins need to be sorted into products. Also i find the service can be lame at times and in store prices aren't consistent with online, so you have to quote their online price to get the discount.
