Did you join Amazon Mom last year when it was offered for free? Then you need to know about these changes. Here’s what I got–

The Amazon Mom program is changing in 2012 and we want to make sure you know about it. Some of these changes affect your membership. Here’s how:

• Starting on January 24, 2012, the maximum discount available on diapers and wipes subscriptions will be 20%. This includes a 5% Subscribe & Save discount plus an additional 15% exclusively for Amazon Mom members who are earning free shipping benefits or have an active Amazon Prime membership.
• Customers who join Amazon Mom in 2012 will get three months of FREE Two-Day Shipping benefits. Once the initial free period is over, customers can join Amazon Prime to continue to receive full access to Amazon Mom and Amazon Prime benefits.

Since your free shipping benefits have ended and you have not yet joined Amazon Prime, the additional 15% Amazon Mom discount on subscriptions will expire on January 24, 2012 .

We hope that you have enjoyed the value and convenience of your Amazon Mom membership over the past year. To continue receiving all the benefits of Amazon Mom, join Amazon Prime for $79/year. As a Prime member you’ll receive:

• 20% off diapers and wipes subscriptions with Amazon Mom and Subscribe & Save.
• FREE Two-Day Shipping on millions of items.
• Unlimited instant streaming of thousands of videos with a wide range of content for the whole family, including Sesame Street and Phineas and Ferb.
• A Kindle book to borrow for free each month from the Kindle Owners’ Lending Library.
• Membership sharing benefits: invite up to four household members to share your shipping benefits for free.

So what does all of this mean? For one, I would review your Amazon purchases over the past year and see if it makes sense to pay for Prime. If you’re not going to get a membership, then I’d order diapers and wipes and whatever else you need, now! Before this trial runs out.
