Buying diapers... at Amazon?

Enoch did the first analysis. Here's mine. We currently purchase diapers from Costco which come in packages with 4x the number of diapers of the Jumbo Pack (at least for the UltraTrim). I'll have to check on the pull-ups, which we also buy (or someone can comment on how many and how much). The Costco package, for both Huggies and Pampers, cost $29.99 not including tax. Amazon sells the Jumbo pack for $7.49, and $7.49x4 = $29.96. Since Amazon is in Washington, and I am in California, there is no sales tax. (Though I think technically in California you need to pay the tax for purchases made out-of-state if the products are used here... someone check on that.) Also, when you spend more than $25 on these products, you are eligible for the free super saver shipping. No shipping, no taxes, 4 cents cheaper, and more room in the car on Costco runs - Amazon wins. Just don't wait till the last minute to re-order. It'll take a few days to come.

Here's the breakdown. We have been using the Ultratrim, since that is all Costco carries. The Supreme is their high-end diaper with a "more comfotable fit". Note that Costco carries 1-2 whereas Amazon has both 1 and 2. Remember to buy four packs to get free shipping.

Let me know if this is helpful. Here's the synopsis, Johnny:

Costco ($29.99+tax)
Pros

  • Can replenish the diaper stock in less than an hour (if you don't stop to eat samples and look at electronics)
  • Can stop to eat samples and look at electronics
Cons
  • In Santa Clara county, 8.25% more expensive due to sales tax
  • Have to drive to Costco and wait in line
  • Bulky, no place for plasma screen in car
  • Pain to unload from car

Amazon ($29.96)
Pros

  • Cheaper by 8.25%
  • Arrives at your door
  • Can purchase in pajamas
  • Look at electronics
Cons
  • No samples
  • Cannot wait until last minute

Update
For the time being, if you by in excess of $50 worth of merchandise. Walgreens is actually cheaper. For size 3 UltraTrim, 60 ct., the sale price is $8.99. You would need to buy 360 at $53.94 (14.9¢pd). I'm not sure, but tax may be included. This courtesy of froogle.

Hey thanks first for all the mathwork and second for commenting about the research on my site. Look forward to future savings.

Most supermarkets periodically put their store brand of diapers on sale for way less than what either Costco or Amazon charges for Huggies. Last week, Safeway had a "buy one get one free" sale on its "jumbo" pack of diapers, resulting in a price of 12.5 cents per diaper for the #4 size ($8.49 for 68 diapers). Stocking up during sales at your local supermarket is way cheaper than Amazon or CostCo!

Just remember when stocking up that babies grow very fast and the Huggies weight/size guidelines in particular are unreliable (i.e. your 15 lb baby may be too big for Size 2 even though posted guidelines indicate he's safely within the range). When diapers start to leak, they are too small.

Thanks for doing this great analysis! I'd love to see it for Pull-ups too.

My 2 cents about store brands: I've tried Safeway since they are so much cheaper but they are thinner and cheaply made, and do not hold much pee. Okay for a few hours during the day but not for long periods or overnight.

Yeah, the target brand are amazingly cheap, but we've had some leakage, so back to the huggies we go. I never in a million years would have thought of buying them from Amazon, though.

You've done an awesome analysis here. I buy Pampers from Costo at $29.99 for stage 3, do you have the breakdown? Just kidding.:) They are pretty much the same in price. Another off brand I have tried is Toysrus' house brand, they have 2 types. The higher priced one is better. But I stopped using them bc ever since my daughter became more active, the top part of the diaper started irritating her tummy bc the trim was scratching her as she moved. But I would definately give them a try. When she was wearing stage 2 for 172 diapers and with an instant rebate of $2 bucks, I ended up paying 19 cents a diaper. Great deal!

Well my diapers, Huggies or Pampers, whatever I choose. Are about $1.00 give or take a few cents per package or box, whichever I choose.
Luckily the "Major Baby Retailer" in my town accepts multiple coupons for diapers, wipes, etc. And when I say multiple, I mean ALL coupons, UP to the price of the diapers. I pay tax on diapers, pretty much. Yay!

Sorry Bud! Diapers at amazon just went up to almost 12 bucks! Get your butt to Costco!
