** I'll admit up front... the title of this post is click bait. **
Act 1 - Last week someone sent a picture of a Schnucks brand Red Cream Soda can to me. Nope, I didn't have that can so they said they'd save it for me.
Act 2 - Next June my son is going on a school trip to Washington DC.
Act 3 - I owed the aforementioned person money for my son's trip. So they jokingly said they would sell the can to me for that amount... which happened to be $550.
Epilogue - I gave someone a $550 check and got a Schnucks can in return. So in effect, this was my most expensive can purchase. But looking at it that way, my son gets a free trip to Washington DC next June.
