Finish Dishwasher Empty Packages Inbox

I bought a box of Finish tablets a while back. I do not have the receipt or box as I emptied them into a plastic container. I paid 24.99$ & I believe it was a box of 72 not 100% sure was a while ago. As of today, I have found 8 empty packages. I didn't mind 3-4 but now that's it's up to 8 thought I should let you know. I am not sure if any more empty in my container. I bought them at Costco in Dartmouth Crossing, Nova Scotia. I thought you should know & I am thanking you in advance for taking the time to read my comment.
