I counted up all the diapers I had 130, plus the diapers in George's backpack for the babysitter, and several others I have stashed here and there. The full box was 136 diapers and I paid $39.98.
I listed the diapers on Facebook for $35. Before long I got an offer for $20 on one Facebook group and $25 on another. I declined both those offers with an explanation of my pricing, including the price per diaper on Amazon and at Sam's (generally these two have the lowest prices).
The woman who offered $25 responded that at Target they were $0.19 per diaper (compared to Amazon and Sam's at 30 and 29, and me at just under 27).
So I said, "I guess I will need to go to Target to get size 5s."
Then she said that Sam's had them on sale too, for $0.21 per diaper or $33.98 for a box of 128.
By that time I had already decided to keep them. But I *could not* just let it go. Her math was wrong, by a lot. So I commented, "$33.98/128 diapers is $0.265 per diaper, not $0.21"
I went to Target and checked their diaper prices- not even close to $0.19 per diaper.
I deleted my posts offering diapers for sale. I also took advantage of the sale at Sam's and am now stocked on size 5s. For when we actually run out of 4s.
