BJ's - These were great value for money. Pretty basic nappy, but a good fit, easy to slide on/off and worked very well.
Target - These were probably the best own brand nappy we tried, they worked great and felt the nicest.
BabiesRUS - This was a surprise as they were the worst. They felt pretty horrid, were very thin but they were easy to put on.
We tried a variety of bathing products from Target, the sleep time body wash, shampoo and hair detangler, equivalents to the Johnson and Johnson line of products. We found these to be just as effective and pleasant to use and certainly worth the savings offered.
Own brand food. BJ's formula was significantly cheaper than the branded stuff and because all formula goes through the FDA, they're all essentially the same and as healthy so you might as well get the cheapest. Target, Hannafords and other stores now carry their own brands which is great, but BJ's is still the cheapest we found.
Snack foods, those cheese puffs and crackers etc. Hannafords have a good line, but so do Target and they are often more cheaper, especially when they are doing their deals. The food is pretty good too, including the little lunch pots and food trays for when the kids are a little older. BJ's are now carrying the branded stuff in bulk though and often have coupons for added savings.
Breast Pads. Many were tried, Avent, they were okay but a little thin, but they also have a 100 count for $11 which is the best value for money. Lansinoh, they were pretty good, but probably not the best value for money as they were quite expensive. Medela, were also expensive and not worth the extra cost. The biggest surprise was BabiesRUS, their own brand pads worked out to be almost the cheapest option, but they were great quality pads. The re-usable ones mostly ended up in the bin as they never ended up being practical and being quite expensive to maintain considering the cost and how many you'd need so that you'd have a supply with you while washing a set etc.
