I forgot to post this a few weeks ago.
Just kidding no parable, its straight out story.
Last winter as you may remember my son got mild frost bite on his feet.
Here is my lesson learned-- its never worth it to buy second hand shoes. I learned this when J was a toddler after a few pairs, one just never fit right. Another velcro didn't work any more. I can find shoes on sale for $7-$13 its just not worth it to save maybe $5 off that price for crappy shoes that don't work. (Last year I got Nan brand spanking new nike tennis shoes for $12 on sale at REI)
Yet some reason I decided to try to save money last winter and buy him second hand boots. Yesterday I bought snow boots at walmart for $17 that have a -5 degrees on the label. $17, I tried to save $10 last year on my son's boots and instead ended up with an expensive visit to the doctor to figure out why my son's feet were covered in a red rash and why he wouldn't walk.
Buy used clothes, buy used toys, buy used couches, but save your money and buy new shoes and boots.
