Save $7.50 on Kirkland Signature Diapers from Costco

Advertiser Disclosure: At Slickdeals, we work hard to find the best deals. Some products in our articles are from partners who may provide us with compensation, but this doesn’t change our opinions.

Right now, Costco members can save $7.50 on Kirkland Signature Supreme diapers, sizes 1 through 6, both in-store and online.
Normally, these diaper packs cost between $29.99 and $35.99, depending on size. From now through April 7th, however, sizes 1 and 2 will go for $22.49 and sizes 3 through 6 will be $28.49.
Non-Costco members can still buy the diapers, but they’ll incur a 5% surcharge.
There is a limit of two per member, however Slickdealer Raphy reports that, “Costco limits are per day.” Did I mention there’s also free shipping?

Each box contains a one month supply (depending on the baby) and comes in two adorable animal designs. But cuteness aside, how good are these diapers?
Slickdealer Cmoney100g says, “Kirkland diapers are made by Huggies, they are great!” For a good comparison, Jnads adds they are, “basically somewhere between Pampers Baby Dry and Swaddlers. Closer to Swaddlers.”
Another Slickdealer reports they’ve “been using these since our little one was 6 months old and haven’t looked back!”
Kirkland Signature Supreme diapers feature a quick draw liner to help keep your baby’s skin dry, as well as a wetness indicator. When it’ time to change your baby’s diaper, the indicator will change color from yellow to blue.
Here’s a handy quantity breakdown with weight recommendations:

  • Size 1: 192 diapers/box (up to 14 lbs.)
  • Size 2: 174 diapers/box (12-18 lbs.)
  • Size 3: 198 diapers/box (16-28 lbs.)
  • Size 4: 180 diapers/box (22-37 lbs.)
  • Size 5: 150 diapers/box (27 lbs. and up)
  • Size 6: 120 diapers/box (35 lbs. and up)
