I've got a lot to say on this topic so I'm just going to have at it!
-First, I recommend that you set up a junk email account that you can use just for discounts and coupons. This way your primary inbox will not become inundated with promotional materials. Gmail from Google is my personal favorite because they have an excellent spam filtering system.
-Be on the lookout for cheap or free subscriptions to parenting magazines. These magazines usually have great coupons like 20% of diapers from Amazon! Some magazines to consider are Parents, Parenting, American Baby, Baby Talk and more. Keep your eyes open for discounts on these 'zines from daily deal sites like Groupon and Eversave.
-Send complimentary emails to your favorite companies telling them how much you love their products. Nine chances out of ten they will thank you by sending you coupons! I mentioned this before in my post What your wallet can expect when you're expecting and also provided a list of companies and their contact information. Check it out!
-Look into specialty points programs like Pampers Gifts to Grow, Huggies Enjoy the Ride Rewards and Upromise. Programs like these offer points as incentives to buying certain products. If you're a die-hard Pampers buyer, for instance, you might as well get rewarded for it!
-I highly, highly recommend joining Amazon Mom if you haven't done so already! This is a free program not just for moms but for dads and grandparents as well. An Amazon Mom membership includes free 2 day shipping on many items through Amazon Prime. And for every $25 purchase in their baby store, you get another free month of Prime. Be sure to look into the even great deals you can score by using their Subscribe and Save options!
-Before you make large purchases, think about it you're buying something that might be for sale in the classifieds or online on craigslist. Many baby items like strollers and highchairs are available in excellent used condition for a fraction of the cost of buying new!
-Don't pay full price for anything! Shop stores like Babies R Us and BuyBuyBaby. These two stores are in direct competition with one another and usually accept their competitor's coupons. It's also helpful to know that BuyBuyBaby and Bed Bath & Beyond are sister stores so you can used a 20% Bed Bath coupon at BuyBuy. One time at my local BuyBuy store I didn't have a 20% coupon on hand but they told me to come back within 30 days with my receipt and a valid coupon and they would credit me the 20%!
-There are some great online retailers for baby products as well. Don't forget to comparison shop a la the Internet! Sites like Diapers.com and Drugstore.com both have great free shipping options as well.
