I always seem to get a boot prints on the books I buy on Amazon. I don’t really buy from Amazon any more but the amount of boot prints I’ve received over the years is a lot! The latest book I ordered came unbelievably spotless. It was about $4 AUD including shipping for a book that would usually cost me $50+ shipping from USA (it was sheet music) so I was very happy. The original delivery date they gave me was delusional so I paid it no mind when it passed. Two days after it, I get an email saying they’re refunding me $3 for the inconvenience, and my spotless book arrived the next day. Three days late is a rounding error in postage delivery timelines where I live. I’m still bewildered by the whole experience to be honest, but hey, almost free expensive sheet music book. Definitely low risk for that purchase.
