    Thank you! I like shopping at Costco and I look forward to this post!

    • Liza (Hip Sidekick)

      You’re welcome Tracey! 🙂

    I’ve been using ROC Retinol for quite some time now & notice some diminished wrinkles on my face. I’m transitioning to a higher percent retinol for my face now. I’ve purchased the retinoid without perscription from a different country online for cheap.

    • MP

      Btw, ROC Retinol is gentle enough for beginners. I never peeled as some do from higher percentage of retinoid. And it seems to be effective. But I recommend to slowly build up to a stronger product for best effect.

    • MP

      Just wanted to mention for those interested. After using ROC Retinol, I’ve used SkinMedica Retinol Complex .25 and it’s a great transition in between the strong retinoid I ordered overseas and ROC Retinol. It’s a great product to stay young looking.

    • Miriam Phinney

      Would you share or give a hint where/how?
      I am turning 50 this month and would love to work on my face/wrinkles that are starting.

      • riss

        I’m turning 50, too, on the 17th 🙂 I started late with skin care. Didn’t even use moisturizer until I was in the late 30’s. I started with non prescription retinoids, and I wasn’t really happy with just that, so I asked my doctor for Retin-A. Pricey and my insurance doesn’t cover it. So after paying full price, I started getting it overseas. Started with 0.025, now I’m on 0.05 %. There are days that my wrinkles are noticeable, like when I don’t get enough sleep, it really shows. Retin A causes my skin to flake, even after using it for so long and only 3x week, so I followed it with moisturizer.

    Thank you so much for this post. This is super helpful in planning.

    • Liza (Hip Sidekick)

      You’re very welcome Cindy! Glad to know it’s helpful to you! 🙂

    Tasty Bite Madras Lentils 8pks are $4 off with a limit of 10. They are normally $11.99, so the discount makes them $7.99. One package is at least $3 at Albertsons and not much less than that at Walmart if they carry it at all.

  5. DJ

    Looks like I will be using my reward check at Costco. Why do I feel like I’ve been robbed after checking out at Costco 🤣?

    • mayd2bz

      I always cash out the reward check at the cashier and charged my Citibank Costco for my shopping trip. That way I feel I could keep earning the reward and use the cash for something else.

  6. Bella

    The Yasso mint chip bars are really, really good! I was hesitant to try them but they are 100 calories of yum!

  7. Sam

    I think Costco sales are going down. I don’t see much lately.

  8. Judy Trac @ Lipscomb

    I don’t see that many sales when I am there

  9. Judy Trac @ Lipscomb

    Costco has a promotion on Dove Men+Care products for the NCAA Final Four. $2 on Dove Men+Care Fresh & Clean Shampoo + Conditioner. Plus there is an Ibotta $1.50 on the 2-in-1 Shampoo Conditioner. 🙂
