Another beautiful spring day has come and as usual brought with it an abundance of Costco sales!

The weather is finally seeming to catch up with the calendar, but it can be forgiven… Seems like the forecast for us is lookin’ good for the next week, sun, sun, sun and a little bit of rain.

Which we all know the saying “April showers brings May snow, which brings May Summer and black flies and flowers”

Well I’m not well versed in these sayings, but I think that’s how it goes?

…April showers brings May…. Sales???

At least that one is partially correct!

Springtime laundry detergent -2.50 @ $9.99

Post Shreddies 1.24 kg -2.00 @ $4.99

Hellman’s real mayonnaise 1.8L -2.00 @ $5.49

Haggar cool 18 golf short men’s size 30-42 -6.00 @ $11.99

Buffalo T-shirt mens size S-XXL -5.00 @ $7.99

Dawn advanced power liquid dish detergent 3 x 709ml -2.00 @ $7.49

Centrum womens/mens multivitamins 250 tablets -6.00 @ $19.99

Junior Advil 100mg grape flavor 80 chewable tablets -4.00 @ $14.99

There’s lots to take in this week folks, so grab your shopping list and get planning!

Hopefully you all had a nice weekend, I know we did. We’re still enjoying the abundance of yard work there is, though it’s hard to know where to stop sometimes. It’s like you trim some scraggly brush in front of you and then look up and see another scraggly brush a few feet ahead of you, so you cut that back, but then guess what? You see 2 of them one to the right and one to the left, well what now??? (the answer is walk away and relax!) Which we did today, for the most part. We finished up a bit of mulch moving, but otherwise it was pretty a pretty low impact day.

It was also our 14th anniversary today. As such we made a nice big dinner, had cupcakes and I’m now very tired and full… So It’s bed time.

Don’t be sad!!! Just scroll down a little bit and you’ll be enlightened by over 160 sales!

That’s enough Monty Python for the night.

See you soon folks, have a great couple of days!

  1. Thanks for the blog every week!
    I think this week the picture of the orgnaika doesn’t match up with the price. I got excited but the label reads as a different product.

  2. Can one ever have enough Monty Python?? 🤔
    Yesterday, I declared it “worst Victoria Day ever”!!
    Here it was cold, windy, rainy, foggy and all ‘round awful. Plus no fireworks 💥…. not that there was going to be any. I love 💥💥!
    That said, big congratulations to you on your 14th anniversary 🎉 🙌 that is an accomplishment worth noting!
    Btw, black flies are the devil’s spawn. We have them too and this cool weather just makes their season last longer 🤬. I have noticed that after so many years of bites, they aren’t as itchy and don’t swell up as much anymore. Maybe I’ve built up a bit of immunity? If you use bug spray, try wetting a paper towel with it and tucking an end into the neck of your t-shirt at the back. It seems to help. I also use one of those bug hats too. Good luck!

  3. Thank you so, so much for your post every week!
    And how did you get the pics up so fast – I thought all Ontario Costco were closed on Victoria Day ?!!
    A few notes (and i only checked cuz i needed price adjustments on the first 2)
    Brookside Variety Pack (40 x 20 g) sale finished May 17
    Basse Power Mix (pic is posted twice) sale finished May 17
    Hellman’s Real Mayonnaise sale finished May 17
    Congrats on your Anniversary!

    Thank you for all your hard work, keeping us up to date with all the sales.

    Nice to hear about what’s going on in your neck of the woods 🙂

  5. I live an hour away from Costco so this makes it easier to plan my trip.
    If you happen to see the tandem kayak on your next visit could you add it to the list?
    It usually comes out after they sell the single kayak.
    Thank you
    So glad I discovered your blog!

  6. Thanks for the pics.
    Costco is a funny beastie: they have the KS tex mex cheese on sale and the guacamole too. Last week, you had to be an EXECUTIVE member to get the tex mex cheese and guacamole on sale. Now ‘regular’ Costco members can get the same products on sale, but not pay the price of Executive membership. Did they think we would not notice?

  7. Happy Anniversary!!
    It’s my parents 53rd anniversary today 🙂

    I agree with Jan, you can never have enough Monty Python, especially with John Cleese!!
    Lots and lots of sales this time!! Will have to make a budget along with my list!

    Enjoy your week!

  8. Hi Ilona, that may only be the case in some warehouses since it isn’t an “across the board” discount for all warehouses in eastern Canada. For reference, either scroll up to “Costco Flyer Sales May 18-24” or look on It’s possible that those products you mentioned didn’t sell well with the Executive Membership coupons (especially since they weren’t mailed out this time) so some individual warehouse managers chose to discount them again to improve sales.
    Hope that helps! Cheers!

    • Thanks Jan in Waterdown. You are correct. We just got back from Costco. The KS tex mex cheese was regular price. The KS probiotic yogurt that Executive members had a deal on, was reduced for ‘regular’ members. And we got the guacamole 🙂
