I have a 7 month old daughter and those of you who have children already know that babies are expensive. One way I save money on diapers, wipes, gears, shoes, etc. is by using Diapers.com and Vistaprint.
Here's how: I availed of Diapers.com's $10 discount off the first order of diapers with $49 minimum purchase. You can do the same by using referral code SHOP4LESS at checkout. Orders over $49 receive free shipping and they ship fast! It beats lugging baby to the store to haul ginormous boxes of diapers and wipes home.
Once you're a customer, you can participate in their Referral Program in which you receive $1 credit for every new customer you refer PLUS a $1 for each additional order they place. The new customer receives a $10 discount upon sign-up. You can then use your credits for anything they carry. There's no limit to the number of credits you can earn but you must use them within 6 months or they will expire.
Once you have a referral code, you want to e-mail it to your friends and family, especially mom friends that might find this coupon and website useful. Diapers.com makes it easy for us to do this, they have a Referral Manager feature which will email your friends for you. All you have to do is enter their e-mail addresses. You can also print a personalized coupon or a flier with your referral code on it.
Some of the more creative advertising I've seen are posting it on Craigslist (this is technically a violation of their TOS but it's up to you. We're all adults here) and even eBay! I've listed my referral code on eBay before and signed up a lot of people that way.
Other reasons why I love Diapers.com are: 1) they do price match BEFORE and AFTER you buy so you know you're getting the best price. 2) they accept manufacturer coupons. Simply mail it to them before placing your order. It's really a wonderful website and I highly recommend it.
Another way I advertise my referral code is by printing business cards and postcards from VistaPrint. Yes, it's really free except for shipping and handling. Just be careful to ignore all the other offers they have towards the end. My cards have the Diapers.com website, the $10 off discount offer, and my referral code. I carry and distribute these cards with me everywhere I go.
Prime locations for distributing these cards are the pediatrician's office, the library, and of course, mommy-and-me classes. If you're quite ambitious, find out ALL the pediatrician's office in your town and pay them a visit. No need to make an appointment or anything like that. Just go and leave a few of your cards in the lobby where the parents can see it. You don't want to leave too much that the office thinks it's litter and throw your cards away. Replenish them every week or so.
A friend of mine who lives near a Babies 'R Us leaves her cards on the windshield of cars parked in the BRU parking lot. She said it works as she has tons of credits but I don't know, I kinda feel funny about that. Just throwing that idea out there anyway in case you're as daring as her.
