My family and I have had a few products disappear from the shelfs over the years that we miss. The biggest was an oatmeal based soap from Gerber. You can still find it on the internet at a ridiculous cost - I think from people who hoarded it. Alas we can’t get it.
The other one that has always annoyed me personally was Pert shampoo for oily hair. Nothing else has ever been ‘just right’ between my scalp and my hair.
Of course then there are a lot of the local non-national products that you can’t get in other areas. I remember Bunny bread and RC cola, etc
I loved the old version of Herbal Essense shampoo-circa 1970s. Also like Prell from back then. I was a teenager then.
I think there is still RC Cola here in Wisconsin.
I tried Stevia cola but I get watery eyes from it. Must be allergic to some extent.
I confess to liking McD’s diet Coke on my rare trips through the drive thru for grilled chicken and french fries.
One product my husband misses is Rippin’ Good Cookies. Named for Ripon, WI where the factory was. We can’t find their cookies anywhere and we live in WI.
